hello welcome back to thrifty to share
00:00:07.709 00:00:07.719 today I thought we'd look at capacitors
00:00:10.780 00:00:10.790 some of the safety features of
00:00:13.509 00:00:13.519 capacitors as far as discharging them
00:00:15.400 00:00:15.410 checking the ESR or equivalent series
00:00:18.670 00:00:18.680 resistance of capacitors since it's very
00:00:22.120 00:00:22.130 important in the circuit especially some
00:00:24.099 00:00:24.109 power supplies high frequency
00:00:26.939 00:00:26.949 applications we're gonna start off
00:00:29.439 00:00:29.449 looking at the yo sodium 328 today I did
00:00:37.000 00:00:37.010 a full review of this in one of my
00:00:40.689 00:00:40.699 previous videos if you haven't seen it
00:00:42.610 00:00:42.620 you might want to look at it or at least
00:00:44.350 00:00:44.360 parts of it sums up a lot of the
00:00:46.149 00:00:46.159 operation I'm not gonna go over in
00:00:47.890 00:00:47.900 detail today but I'm gonna use it for
00:00:52.390 00:00:52.400 comparison I also have a little science
00:00:57.250 00:00:57.260 tech the NES are 100 mister version one
00:01:02.229 00:01:02.239 not the version two but I haven't been
00:01:04.810 00:01:04.820 real long version two is a little better
00:01:47.160 00:01:47.170 start off with a quick look at the GM
00:01:50.440 00:01:50.450 328 I won't bore you with the details of
00:01:54.219 00:01:54.229 this one since I've already done a
00:01:55.840 00:01:55.850 comprehensive video a lot of the
00:01:58.330 00:01:58.340 functionality that I figured out about
00:02:00.730 00:02:00.740 it so it doesn't come with a lot of
00:02:03.250 00:02:03.260 literature pretty much comes in the box
00:02:06.160 00:02:06.170 like it is without the backplate I have
00:02:08.440 00:02:08.450 that as I mentioned on the video but it
00:02:11.559 00:02:11.569 doesn't do a really good job with
00:02:12.850 00:02:12.860 capacitance in the air saw so I won't
00:02:15.040 00:02:15.050 included and
00:02:16.090 00:02:16.100 test today it's over you look of the
00:02:19.540 00:02:19.550 meter today unless science tech mes are
00:02:28.210 00:02:28.220 100 this is the version one they got the
00:02:30.760 00:02:30.770 version two out now comes a little um
00:02:41.350 00:02:41.360 manual shows a bit use 100 kilohertz for
00:02:47.560 00:02:47.570 testing
00:02:58.630 00:02:58.640 it does have a backlight it's pretty
00:03:02.110 00:03:02.120 decent
00:03:06.440 00:03:06.450 this one also has a backlight which I I
00:03:09.260 00:03:09.270 didn't mention because it's actually
00:03:10.759 00:03:10.769 pretty nice back
00:03:24.309 00:03:24.319 the leash together
00:03:39.380 00:03:39.390 so we'll let you know the range innocent
00:03:41.690 00:03:41.700 auto and the ESR value whether it's good
00:03:47.140 00:03:47.150 for for 25 volt rated reference and also
00:03:52.610 00:03:52.620 gives you a comparison chart below which
00:03:54.710 00:03:54.720 is pretty handy to have right on the
00:03:58.370 00:03:58.380 meter a lot of those charts are generic
00:04:00.740 00:04:00.750 you'd have to look at the caps
00:04:02.030 00:04:02.040 information directly yeah you would have
00:04:05.660 00:04:05.670 to just look at the like the spec for
00:04:08.360 00:04:08.370 the capacitor manufacturers so where the
00:04:12.110 00:04:12.120 B Rubicon or you'd have to get the
00:04:15.020 00:04:15.030 information off actual captain look up
00:04:18.710 00:04:18.720 the data on the datasheet a reference
00:04:21.560 00:04:21.570 sheet on the cap itself because yes our
00:04:23.990 00:04:24.000 values do do different from manufacturer
00:04:26.900 00:04:26.910 or even they're a series of caps because
00:04:30.490 00:04:30.500 some capacitors are are very good low at
00:04:34.790 00:04:34.800 low ESR capacitors especially for higher
00:04:38.030 00:04:38.040 in applications and how high frequency
00:04:44.570 00:04:44.580 applications should I say the manual is
00:04:47.659 00:04:47.669 really good with the atlas ESR sixty an
00:04:59.480 00:04:59.490 already cut it on here by accident
00:05:01.870 00:05:01.880 it's okay this was the only one that we
00:05:07.640 00:05:07.650 had that does not have a backlight but I
00:05:09.740 00:05:09.750 can honestly say that I never really
00:05:11.840 00:05:11.850 needed this got a really nice bright
00:05:13.610 00:05:13.620 green I'm back into the LCD so never
00:05:21.080 00:05:21.090 really needed it
00:05:27.480 00:05:27.490 and the resistance measurements always
00:05:30.550 00:05:30.560 pretty accurate with this one it does
00:05:36.129 00:05:36.139 like I say capacitance and the
00:05:37.990 00:05:38.000 equivalent series resistance and last
00:05:43.330 00:05:43.340 but not least the BK precision comes
00:05:50.140 00:05:50.150 with the leaves the meter a USB cable
00:05:54.399 00:05:54.409 and this one will communicate with a PC
00:05:57.580 00:05:57.590 based the driver you can download from
00:06:00.010 00:06:00.020 the internet also comes with an AC
00:06:02.740 00:06:02.750 adapter so you're not just relying on
00:06:09.189 00:06:09.199 the battery on the beach testing a lock
00:06:11.700 00:06:11.710 that's kind of Handy to mention a little
00:06:15.999 00:06:16.009 bit about price here I have them in
00:06:18.070 00:06:18.080 order from least to the most expensive
00:06:22.860 00:06:22.870 as of right now Amazon you can get the
00:06:26.550 00:06:26.560 GM 328 for under $20 19:49 was the last
00:06:31.649 00:06:31.659 price that i i've seen on it
00:06:35.760 00:06:35.770 the mes are 100 comes in a lot of
00:06:40.149 00:06:40.159 different name brands this one science
00:06:42.939 00:06:42.949 tech it's at least a lot of them looks
00:06:44.620 00:06:44.630 similar packaging even even down to the
00:06:48.209 00:06:48.219 the chart table yes our table on the
00:06:51.600 00:06:51.610 front of the meter but like they version
00:06:56.050 00:06:56.060 2 is available now with a little more
00:06:57.730 00:06:57.740 features with around $55 to go on price
00:07:01.240 00:07:01.250 on these it does have the hundred
00:07:03.999 00:07:04.009 kilohertz to hit remove the impedance
00:07:07.450 00:07:07.460 off the capacitor when checking the ESR
00:07:10.920 00:07:10.930 it also uses the square wave now that
00:07:16.360 00:07:16.370 they say the diversion to uses a sine
00:07:18.730 00:07:18.740 wave to give a a little bit better
00:07:21.899 00:07:21.909 testing its supposed to have a
00:07:25.659 00:07:25.669 resolution down the point 0 0 1 ohm it
00:07:30.399 00:07:30.409 does the idle display for the bad caps a
00:07:32.439 00:07:32.449 good cat based on a common 25
00:07:36.469 00:07:36.479 electrolytic cap this one uses a nine
00:07:39.799 00:07:39.809 vote but the the version two uses two
00:07:42.439 00:07:42.449 doublea's and I think the version 2 can
00:07:46.610 00:07:46.620 also be USB power which this one has it
00:07:49.040 00:07:49.050 as well the pts are 60 is actually
00:07:58.929 00:07:58.939 becoming obsolete now they had the 70
00:08:01.969 00:08:01.979 model out which looks almost identical
00:08:04.730 00:08:04.740 but this one sells for about 119 if you
00:08:10.909 00:08:10.919 can still find it I believe the 90 of
00:08:13.489 00:08:13.499 the ESR 70 is still selling for about
00:08:17.540 00:08:17.550 the same price like I said with a little
00:08:20.390 00:08:20.400 bit better features on the 879 be it's
00:08:28.820 00:08:28.830 selling for about $2.99
00:08:31.429 00:08:31.439 I think Amazon has it for maybe 263 but
00:08:38.810 00:08:38.820 it's by far the most expensive but I
00:08:45.379 00:08:45.389 won't really get into the complete
00:08:49.699 00:08:49.709 comparison of it because or review of it
00:08:53.120 00:08:53.130 even because it's the LCR meter and has
00:08:55.309 00:08:55.319 a lot more functionality than what we're
00:08:57.290 00:08:57.300 going to get into today just checking I
00:08:59.449 00:08:59.459 just want to stick with Strictly
00:09:01.069 00:09:01.079 capacitance and and yes all on ESR meter
00:09:05.319 00:09:05.329 but checking things like switch mode
00:09:07.670 00:09:07.680 power supplies and know the high
00:09:09.259 00:09:09.269 frequency applications ESR is very
00:09:11.990 00:09:12.000 important and it's a easy check
00:09:13.629 00:09:13.639 sometimes if it's borderline I don't so
00:09:16.400 00:09:16.410 much worry about a cap but this is one
00:09:20.629 00:09:20.639 of the better charts I've seen and I use
00:09:22.550 00:09:22.560 it a lot to go by and I didn't realize
00:09:25.579 00:09:25.589 it till I bought the the peak that this
00:09:28.639 00:09:28.649 like this charts actually in the booklet
00:09:31.300 00:09:31.310 whether they originated or not I just
00:09:33.710 00:09:33.720 use this generic chart I don't know but
00:09:36.740 00:09:36.750 it's the exact same chart and wording in
00:09:40.009 00:09:40.019 the actual book that comes with the
00:09:41.629 00:09:41.639 atlas yes or
00:09:46.770 00:09:46.780 so a little bit of quick rundown of
00:09:51.180 00:09:51.190 course this one has already been
00:09:54.820 00:09:54.830 mentioned that the video previous video
00:09:57.850 00:09:57.860 on this one already tells a lot of
00:09:59.290 00:09:59.300 detail about it I'll go into this peak
00:10:03.310 00:10:03.320 because it has a lot of features as far
00:10:05.770 00:10:05.780 as the 100 kilohertz capacitance and
00:10:08.980 00:10:08.990 equivalent series resistance check it's
00:10:11.440 00:10:11.450 got the automatic discharge which is
00:10:13.510 00:10:13.520 this is the only one that actually has
00:10:15.490 00:10:15.500 that but it does ask that it's less than
00:10:19.210 00:10:19.220 50 volts if the capacitor is greater
00:10:21.700 00:10:21.710 than 50 volts then it will let you know
00:10:24.790 00:10:24.800 on the screen on the atom on the
00:10:27.550 00:10:27.560 automatic analysis and let you know that
00:10:30.900 00:10:30.910 capacitor is greater than 50 volts I
00:10:33.760 00:10:33.770 will show you the voltage read on the
00:10:35.650 00:10:35.660 screen and it will ask you to discharge
00:10:37.690 00:10:37.700 it properly the leads on this little
00:10:41.080 00:10:41.090 meter are very good even though it's a
00:10:45.250 00:10:45.260 little bit of a specialty you can get
00:10:48.070 00:10:48.080 replacement clips and it looks to be
00:10:50.950 00:10:50.960 gold-plated and whenever you short these
00:10:56.680 00:10:56.690 out and do a check it always shows zero
00:10:59.170 00:10:59.180 I mean if it really does a good job on
00:11:01.330 00:11:01.340 the low home scale on the 60 the maximum
00:11:07.450 00:11:07.460 resistance had to do is 20 ohms now the
00:11:10.180 00:11:10.190 70 is 40 ohms so the one that's
00:11:14.050 00:11:14.060 available now we'll go to 40 ohms and
00:11:18.180 00:11:18.190 just to mention the 60 don't have the
00:11:20.830 00:11:20.840 auto boy alerts the 70 has Auto boiler
00:11:23.830 00:11:23.840 to let you know and I thought that was
00:11:26.710 00:11:26.720 gonna that would be a really neat
00:11:28.240 00:11:28.250 feature
00:11:28.800 00:11:28.810 if I were I'm gonna save and I think
00:11:31.510 00:11:31.520 I'll enjoy that because just going
00:11:33.790 00:11:33.800 through checking maybe on a circuit
00:11:36.760 00:11:36.770 board just going through checking
00:11:38.980 00:11:38.990 different caps it'll actually have a
00:11:41.110 00:11:41.120 different tone of what range the ESR is
00:11:44.950 00:11:44.960 so you can possibly go across the
00:11:47.380 00:11:47.390 circuit board and not even have to look
00:11:49.600 00:11:49.610 back up until you hear a different tone
00:11:52.030 00:11:52.040 or beep well maybe you don't hear
00:11:54.040 00:11:54.050 anything at all like it's not reading
00:11:56.079 00:11:56.089 anything
00:11:56.930 00:11:56.940 so I think that's a really good feature
00:11:59.710 00:11:59.720 that capacity range on this one is one
00:12:02.480 00:12:02.490 microfarad to 22,000 and it does really
00:12:06.920 00:12:06.930 good for capacitance and low home checks
00:12:08.990 00:12:09.000 which actually all these ESR means to do
00:12:12.020 00:12:12.030 that it does have the auto power off it
00:12:17.180 00:12:17.190 does take a little 12 volt alkaline
00:12:19.180 00:12:19.190 batteries of the 23:23 a type and it is
00:12:30.260 00:12:30.270 polarity free this one and the GM 328 or
00:12:36.500 00:12:36.510 polarity free you just plug it up or
00:12:38.420 00:12:38.430 hook it up to the capacitor either way
00:12:40.730 00:12:40.740 you get a reef properly these two
00:12:44.780 00:12:44.790 actually want you to do the polarity
00:12:46.460 00:12:46.470 correctly on these as far as the 879 be
00:12:57.100 00:12:57.110 it has a lot of configure you know
00:13:00.170 00:13:00.180 configurable capabilities
00:13:01.820 00:13:01.830 you know from beep out of all the fault
00:13:04.130 00:13:04.140 modes that it comes on to it also has
00:13:07.700 00:13:07.710 the backlight the LCDs really good on
00:13:09.920 00:13:09.930 this meter the case is really good
00:13:13.910 00:13:13.920 quality I do I do read the light became
00:13:19.360 00:13:19.370 stuff I got a little meter here I know
00:13:23.720 00:13:23.730 it's a different subject but they make
00:13:25.550 00:13:25.560 similar things I like a little two kids
00:13:27.820 00:13:27.830 they look 2709 be he's got the little
00:13:32.300 00:13:32.310 magnetic hanger and I just kind of keep
00:13:35.390 00:13:35.400 hanging up on my Beach it's the one I
00:13:37.760 00:13:37.770 have my tweezers hook to for some of the
00:13:40.580 00:13:40.590 circuit board probing it's a good little
00:13:43.370 00:13:43.380 eater it's a true RMS I have no issues
00:13:45.590 00:13:45.600 with it
00:13:46.040 00:13:46.050 this meters may be very similar as far
00:13:48.650 00:13:48.660 as the case it has the USB capability to
00:13:53.540 00:13:53.550 download the driver it can be powered by
00:13:56.330 00:13:56.340 the wall adapter and it's takes the
00:14:00.380 00:14:00.390 generally test like the 1 kilohertz test
00:14:05.090 00:14:05.100 for 4.0 1 microfarad are smaller and
00:14:08.840 00:14:08.850 when you get above 10
00:14:10.310 00:14:10.320 microfarad it wants you to use the lower
00:14:12.200 00:14:12.210 like 120 Hertz frequency which seems a
00:14:16.010 00:14:16.020 little unusual to me I know that
00:14:17.750 00:14:17.760 typically 100 kilohertz is what
00:14:19.820 00:14:19.830 manufacturers test their ESR that's a
00:14:24.680 00:14:24.690 typical thing not across the board but
00:14:27.640 00:14:27.650 you can also select besides the
00:14:31.340 00:14:31.350 frequency selection you can you can
00:14:33.530 00:14:33.540 check and change this one only goes up
00:14:39.080 00:14:39.090 at 10 kilohertz from 100 Hertz and it
00:14:42.860 00:14:42.870 steps up to 10 kilohertz this one like I
00:14:45.650 00:14:45.660 said does not do 100 kilohertz the the
00:14:48.890 00:14:48.900 880 model that they make will but I
00:14:51.680 00:14:51.690 think just 399 so to meet us a lot of
00:14:56.420 00:14:56.430 money for 4 meter but somebody uses it
00:14:59.630 00:14:59.640 every day they have that much
00:15:02.480 00:15:02.490 functionality it's probably worth it it
00:15:06.470 00:15:06.480 defaults on powerup it defaults to
00:15:13.250 00:15:13.260 parallel and 1 kilohertz for the check
00:15:22.040 00:15:22.050 we can hold this button down from P to s
00:15:26.570 00:15:26.580 and go to SC off or series and we can go
00:15:31.340 00:15:31.350 frequency up one to ten and to go down
00:15:34.579 00:15:34.589 to a hundred 100 Hertz one twenty one
00:15:38.000 00:15:38.010 kilohertz ten think he'll Hertz so this
00:15:42.889 00:15:42.899 one has a lot of functionality a lot of
00:15:44.840 00:15:44.850 different ways to check yes alright
00:15:48.949 00:15:48.959 capacitance values which sometimes can
00:15:51.560 00:15:51.570 be a little confusing it comes up by
00:15:54.260 00:15:54.270 default in the parallel mode and it
00:16:00.769 00:16:00.779 actually checked I think you check
00:16:03.680 00:16:03.690 capacitance better as we get into it I
00:16:05.930 00:16:05.940 think it check capacitance better
00:16:07.460 00:16:07.470 typically in parallel mode but in series
00:16:11.600 00:16:11.610 mode it's seen the show a true ESR so
00:16:16.870 00:16:16.880 we'll look at that a little more as we
00:16:18.920 00:16:18.930 get into it but this one also does not
00:16:21.620 00:16:21.630 have a discharge auto discharge it tells
00:16:25.550 00:16:25.560 you to discharge the capacitor before
00:16:27.920 00:16:27.930 testing so we'll look at now we'll go
00:16:32.780 00:16:32.790 through a few tests with these and
00:16:34.100 00:16:34.110 compare them there's a safety precaution
00:16:38.930 00:16:38.940 we're gonna be dealing with some very
00:16:41.150 00:16:41.160 large and very powerful capacitors this
00:16:44.870 00:16:44.880 one in particular is 20 2 micro farad at
00:16:49.000 00:16:49.010 450 volts rate it's a lot of charge it's
00:16:54.170 00:16:54.180 a pretty heavy capacitor and even this
00:16:56.569 00:16:56.579 one it may look small to comparison but
00:16:58.760 00:16:58.770 it's a 560 micro farad at 200 volts so
00:17:03.139 00:17:03.149 it's also a high rated capacitor so what
00:17:07.220 00:17:07.230 I'm gonna do is charge it up with a
00:17:12.069 00:17:12.079 instead of my power supply I have this
00:17:15.079 00:17:15.089 56 volt battery is fully charged that
00:17:18.110 00:17:18.120 are charged it up very quickly I have a
00:17:23.650 00:17:23.660 470 ohm resistor with some leads and
00:17:27.549 00:17:27.559 these leaves have a little resistance to
00:17:30.049 00:17:30.059 they're not the best quality
00:17:32.380 00:17:32.390 actually works out pretty good for
00:17:35.110 00:17:35.120 discharging capacitors if you want to
00:17:39.740 00:17:39.750 charge this up always when charging the
00:17:42.080 00:17:42.090 capacitor you want to keep your polarity
00:17:44.420 00:17:44.430 correct if you don't it can blow up in
00:17:46.190 00:17:46.200 your hand your face it's a quick charge
00:17:51.920 00:17:51.930 there straight on straight across this
00:18:01.420 00:18:01.430 capacitor close to a lethal level now we
00:18:08.510 00:18:08.520 cut it on immediately it says 52 volts
00:18:11.750 00:18:11.760 please discharge or capacitor now it
00:18:16.160 00:18:16.170 went down enough that it's actually
00:18:17.540 00:18:17.550 discharged and automatically discharged
00:18:21.770 00:18:21.780 that intensity just that quick this
00:18:23.450 00:18:23.460 meter is really good at doing that but
00:18:29.270 00:18:29.280 always be very very careful and make
00:18:32.990 00:18:33.000 sure you capacitors you know the method
00:18:36.560 00:18:36.570 of taking and running a screwdriver
00:18:37.880 00:18:37.890 across it it works well to make sure
00:18:40.760 00:18:40.770 that it doesn't have enough charge to
00:18:43.760 00:18:43.770 hurt you
00:18:44.570 00:18:44.580 he he trailed it to art then hurt you
00:18:47.080 00:18:47.090 but also I'm gonna charge this one up
00:18:51.710 00:18:51.720 and it's gonna art too now even even
00:18:59.690 00:18:59.700 charging this thing up at that level
00:19:05.740 00:19:05.750 which is a 450 vote now but it is saying
00:19:11.720 00:19:11.730 is 55 volts
00:19:12.980 00:19:12.990 safely discharges so it's letting you
00:19:14.840 00:19:14.850 know it warns you unless you know that
00:19:19.190 00:19:19.200 it can't discharge it at that level
00:19:20.810 00:19:20.820 safely so at this point we can take our
00:19:24.190 00:19:24.200 resistor and leads and we can discharge
00:19:28.400 00:19:28.410 it
00:19:32.659 00:19:32.669 you can see them leader there
00:19:37.620 00:19:37.630 and it is discharged this time I have
00:19:47.049 00:19:47.059 this large capacitor charged up again I
00:19:49.180 00:19:49.190 want you to be able to see the voltage
00:19:51.760 00:19:51.770 on the screen and by taking the resistor
00:19:56.740 00:19:56.750 and a jumper and going across I want you
00:20:03.100 00:20:03.110 to be able to see how slowly it
00:20:07.810 00:20:07.820 discharges it's rapid enough to
00:20:10.539 00:20:10.549 discharge quickly but yet it doesn't do
00:20:16.030 00:20:16.040 it in a high rate in the arc because
00:20:22.510 00:20:22.520 honestly with this with this capacitor
00:20:24.940 00:20:24.950 there 450 volts charged I would not want
00:20:28.180 00:20:28.190 to discharge it straight across for the
00:20:32.230 00:20:32.240 bus so would demonstrate that with just
00:20:35.890 00:20:35.900 56 bolts on it it's pretty uh it's
00:20:39.190 00:20:39.200 pretty big bang so once again we got
00:20:46.090 00:20:46.100 this large capacitor charged up this is
00:20:49.930 00:20:49.940 right at 55 volts on it
00:20:52.230 00:20:52.240 55 volts at 2200 microfarad is is fairly
00:20:58.480 00:20:58.490 large but it's nothing compared to the
00:21:00.730 00:21:00.740 450 volts so it's a pretty big pop so
00:21:09.210 00:21:09.220 enough to scare you so that way by using
00:21:16.210 00:21:16.220 a resistor it can be a little less
00:21:19.120 00:21:19.130 intense but nonetheless at least
00:21:22.539 00:21:22.549 Alicia's use a screwdriver or a jumper
00:21:24.700 00:21:24.710 to make sure they are totally discharged
00:21:27.600 00:21:27.610 before moving forward because some of
00:21:30.070 00:21:30.080 these can be at lethal voltages most
00:21:33.520 00:21:33.530 circuits in there either in circuit most
00:21:36.340 00:21:36.350 of them do have a bleed resistor which
00:21:39.549 00:21:39.559 you can't always rely on that they can
00:21:41.590 00:21:41.600 be faulty as well and you can't you
00:21:43.990 00:21:44.000 can't always rely that they actually
00:21:45.340 00:21:45.350 have one in circuit either so always
00:21:49.710 00:21:49.720 rather safe than sorry now not only for
00:21:53.710 00:21:53.720 your sake but also the meters because
00:21:55.390 00:21:55.400 not all of them have a safe to do it in
00:21:57.190 00:21:57.200 if the peak does so I always keep that
00:22:00.130 00:22:00.140 in mind once again I have these
00:22:06.270 00:22:06.280 capacitors charged up to about 55 56
00:22:09.310 00:22:09.320 votes discharges straight across the
00:22:11.890 00:22:11.900 terminals this 560 micro farad at 200
00:22:20.830 00:22:20.840 volt also charged up to about 56 volts
00:22:28.470 00:22:28.480 so that's the difference I'm putting a
00:22:33.190 00:22:33.200 resistor across or just below 50 folks
00:22:36.909 00:22:36.919 just letting that discharge it so again
00:22:41.110 00:22:41.120 this was charged up to a truth 450
00:22:44.950 00:22:44.960 voltage all that it would uh it would
00:22:47.020 00:22:47.030 take a chunk out of the screwdriver
00:22:48.340 00:22:48.350 shank so just always be aware of what
00:22:52.180 00:22:52.190 you have in comparison to their eye both
00:22:57.990 00:22:58.000 or all or electrolytic but if there's a
00:23:01.030 00:23:01.040 big difference between this little small
00:23:04.810 00:23:04.820 one and and of course the larger variety
00:23:16.370 00:23:16.380 okay so one thing to remember about
00:23:19.600 00:23:19.610 capacitor we're actually two things to
00:23:23.330 00:23:23.340 remember about capacitor and ESR
00:23:27.170 00:23:27.180 check-in is the first thing safety we
00:23:30.470 00:23:30.480 covered that cover yourself
00:23:32.600 00:23:32.610 make sure you capacitor discharge they
00:23:34.430 00:23:34.440 can harm you especially the larger
00:23:37.100 00:23:37.110 variety they can go up to 450 volts of
00:23:39.290 00:23:39.300 high-capacity but anything over over 50
00:23:43.370 00:23:43.380 volts can be deadly so be careful the
00:23:48.080 00:23:48.090 next thing to really consider when you
00:23:50.030 00:23:50.040 do an ESR testing is think about the the
00:23:54.500 00:23:54.510 low resistance of the test what your
00:23:57.800 00:23:57.810 chicken is ultra low or very low ohms so
00:24:03.080 00:24:03.090 the resistance does matter so if we use
00:24:05.690 00:24:05.700 this GM 328 we can very easily put some
00:24:10.310 00:24:10.320 clips in here and the lows if socket and
00:24:14.690 00:24:14.700 close it up so it makes it real handy
00:24:18.950 00:24:18.960 right well for some things the reason
00:24:23.750 00:24:23.760 that zip suck it's so important is it's
00:24:25.820 00:24:25.830 very low ohms to the trace so it's
00:24:29.840 00:24:29.850 designed to be as close as you can
00:24:32.300 00:24:32.310 especially ESR low ohms reading if we
00:24:35.540 00:24:35.550 were to short this out and do a test
00:24:37.190 00:24:37.200 right now it's a bit one of the best
00:24:40.370 00:24:40.380 ways to do this one two three is showing
00:24:45.350 00:24:45.360 a resistance of one point three three
00:24:46.880 00:24:46.890 ohms and I did that just to show that
00:24:50.870 00:24:50.880 how crappy some leaves can be it's the
00:24:53.000 00:24:53.010 bees look cheap like eBay the leaves are
00:24:57.020 00:24:57.030 just are just that much resistance and
00:24:59.000 00:24:59.010 it's a really crappy connection we can
00:25:02.210 00:25:02.220 we can remedy some of that but just to
00:25:04.670 00:25:04.680 show the little crimp don't forward it
00:25:07.400 00:25:07.410 back they're not even soldered so just
00:25:10.010 00:25:10.020 be careful what you do with leads this
00:25:13.220 00:25:13.230 is probably an exaggerated case because
00:25:15.050 00:25:15.060 the lead to such poor quality but it
00:25:17.570 00:25:17.580 just goes to show that it doesn't matter
00:25:20.470 00:25:20.480 because what we're checking for is down
00:25:24.950 00:25:24.960 some of these capacitors the larger they
00:25:27.890 00:25:27.900 get like point zero
00:25:29.720 00:25:29.730 so you can see we already out of spec
00:25:33.220 00:25:33.230 for a neck for an example I'll just use
00:25:36.650 00:25:36.660 this one for an example let's say 2200
00:25:40.610 00:25:40.620 microfarad at 16 volts put it on here
00:25:45.380 00:25:45.390 with these leaves let's see what IES are
00:25:49.340 00:25:49.350 at the test tells us checking the
00:25:54.200 00:25:54.210 capacitance capacitance checks good
00:25:56.720 00:25:56.730 which you know through the resistance
00:26:01.100 00:26:01.110 and the wire the capacitance show up
00:26:02.660 00:26:02.670 okay typically just a little bit lower
00:26:04.490 00:26:04.500 but 0.75 on that's that's pretty bad if
00:26:11.240 00:26:11.250 we look at the chart here at 16 volts we
00:26:14.120 00:26:14.130 should be at point zero seven so well
00:26:18.350 00:26:18.360 that's a bad cap well let's do the same
00:26:21.620 00:26:21.630 test this time putting it across the ZIF
00:26:27.830 00:26:27.840 socket directly
00:26:36.810 00:26:36.820 and point 1 1 so it's really close so
00:26:42.300 00:26:42.310 according to this we're still a little
00:26:46.710 00:26:46.720 bit higher sorry we're still a little
00:26:48.720 00:26:48.730 bit higher than it should be but I think
00:26:53.160 00:26:53.170 that capacitor is ok it's not showing a
00:26:55.590 00:26:55.600 tremendous variance from from the
00:26:58.800 00:26:58.810 typical chart and at that point if it
00:27:01.680 00:27:01.690 really matters to you I would look up
00:27:03.360 00:27:03.370 actual manufacturer and see you 200
00:27:05.370 00:27:05.380 kilohertz what it actually the
00:27:07.680 00:27:07.690 manufacturer states the specs for that
00:27:09.540 00:27:09.550 capacitor should be so with that being
00:27:13.080 00:27:13.090 said this look capacitor does a little
00:27:15.930 00:27:15.940 Kester does do a good job with
00:27:17.340 00:27:17.350 capacitance an ESR just always keep in
00:27:19.890 00:27:19.900 mind it matters about leads which it's
00:27:24.720 00:27:24.730 also one reason all these meters come
00:27:26.760 00:27:26.770 with little short leads even even this
00:27:30.990 00:27:31.000 high-dollar meter has got some pretty
00:27:32.940 00:27:32.950 short leads and these are a little
00:27:37.230 00:27:37.240 longer but they are high quality really
00:27:39.720 00:27:39.730 high quality leads and they do work well
00:27:43.580 00:27:43.590 but we always have to zero WiDi meter
00:27:46.740 00:27:46.750 and we have to make sure that the leads
00:27:49.320 00:27:49.330 are short it's possible doing the 100
00:27:53.220 00:27:53.230 kilohertz check the ESR okay now we're
00:27:59.160 00:27:59.170 back with the GM 328 I got a few
00:28:02.220 00:28:02.230 capacitors here to check I had a bunch
00:28:04.200 00:28:04.210 more up there and even some more back in
00:28:06.240 00:28:06.250 the back of the beach to check I
00:28:09.330 00:28:09.340 realized it was going to take a lot of
00:28:11.070 00:28:11.080 time didn't want to bore you to death to
00:28:12.720 00:28:12.730 the video try to keep it as short as we
00:28:15.630 00:28:15.640 can so I just got I got four capacitors
00:28:19.290 00:28:19.300 up here one of them I know as a failed
00:28:21.180 00:28:21.190 capacitor I didn't actually keep many
00:28:24.360 00:28:24.370 from repair jobs but I did actually have
00:28:27.480 00:28:27.490 this one you can see the very typical
00:28:30.860 00:28:30.870 boat and the swell factor of this
00:28:35.870 00:28:35.880 capacitor it was a good a good name
00:28:39.240 00:28:39.250 brand and a good style capacitors just
00:28:45.240 00:28:45.250 over time his actions over 20 years old
00:28:47.160 00:28:47.170 so just
00:28:49.529 00:28:49.539 time for they don't they don't have a
00:28:51.239 00:28:51.249 very long life electrolytic so we'll
00:28:54.509 00:28:54.519 check will check these forward one known
00:28:56.820 00:28:56.830 bad one and then I also wanted to take
00:29:00.330 00:29:00.340 time to get into some well do some in
00:29:02.460 00:29:02.470 circuit just on a board that I have got
00:29:06.389 00:29:06.399 a large cap here we got some I probably
00:29:08.519 00:29:08.529 check this one here on board
00:29:13.460 00:29:13.470 got a little Stepford driver here
00:29:15.690 00:29:15.700 probably check this big cap here it's
00:29:18.419 00:29:18.429 one of the during my move it got dented
00:29:21.180 00:29:21.190 up we'll check it and see hey is it
00:29:22.830 00:29:22.840 still okay check okay or special if it
00:29:27.690 00:29:27.700 doesn't show short or anything like that
00:29:29.310 00:29:29.320 so so we'll get into testing with this
00:29:32.099 00:29:32.109 GM 328 first I got the large 2200
00:29:36.149 00:29:36.159 microfarad 450 vote capacitor I'm gonna
00:29:39.269 00:29:39.279 cut this bench light up I believe it'll
00:29:41.039 00:29:41.049 be better they glare on the screen but
00:29:46.469 00:29:46.479 first of all let me uh any zero after
00:29:49.049 00:29:49.059 leaves here or at least show you what it
00:29:52.259 00:29:52.269 is we can't go through round we can go
00:29:57.930 00:29:57.940 through a person we can't go through a
00:29:59.430 00:29:59.440 procedure and actually point zero seven
00:30:02.729 00:30:02.739 so you can go through and self-test and
00:30:05.369 00:30:05.379 zero out the leads wherever they are let
00:30:08.129 00:30:08.139 it go through a calibration check but we
00:30:11.609 00:30:11.619 know we point zero seven a point zero
00:30:15.659 00:30:15.669 eight what I read earlier I wrote that
00:30:17.310 00:30:17.320 down and we getting point one five
00:30:22.930 00:30:22.940 went one 5 2012 micro fire
00:30:27.220 00:30:27.230 okay wrote that down let's go onto the
00:30:29.960 00:30:29.970 next one this is the 560 microfiber 200
00:30:40.850 00:30:40.860 volt and it's showing point four eight
00:31:02.790 00:31:02.800 point one five that's what I got earlier
00:31:06.870 00:31:06.880 I think I had a bad connection on them
00:31:08.700 00:31:08.710 it doesn't matter they got a really
00:31:11.430 00:31:11.440 least need to be on there good and tight
00:31:14.300 00:31:14.310 you talking about
00:31:16.110 00:31:16.120 less than an own bag it don't take much
00:31:17.880 00:31:17.890 to change the reading yeah point one
00:31:22.080 00:31:22.090 four that's more like what I was getting
00:31:24.210 00:31:24.220 earlier when I checked it alright now
00:31:27.960 00:31:27.970 this is the one that's known defective
00:31:29.880 00:31:29.890 one of the test here is with all the
00:31:32.100 00:31:32.110 meters pick up the good ones being close
00:31:34.680 00:31:34.690 to in tolerance and will they pick up
00:31:36.330 00:31:36.340 the bad one being defective and we show
00:31:43.980 00:31:43.990 on a 1274 nanofarad and and look at that
00:31:48.720 00:31:48.730 as point 0.14 K ohm 9.14 so poaches loss
00:31:56.940 00:31:56.950 of 23% so we're showing there's 250 volt
00:32:02.100 00:32:02.110 20 2 micro farad and showing almost any
00:32:06.480 00:32:06.490 capacitance where it should be and then
00:32:09.150 00:32:09.160 the resistance is showing way high so
00:32:11.880 00:32:11.890 some of these meters won't even read
00:32:13.890 00:32:13.900 that high so it picked up the effective
00:32:17.040 00:32:17.050 one definitely picked it up as defective
00:32:19.640 00:32:19.650 we have a 68 hundred microfarad at 35
00:32:23.460 00:32:23.470 volts
00:32:41.190 00:32:41.200 point one o 8313 this one actually reads
00:32:47.610 00:32:47.620 hi by all the meters next we'll try do
00:32:55.409 00:32:55.419 an insert it check
00:33:06.240 00:33:06.250 these leads do have some loss but it's
00:33:08.760 00:33:08.770 not it's not real bad that's point zero
00:33:12.420 00:33:12.430 seven relative alright so we have a 25
00:33:21.300 00:33:21.310 14 at point one one well off so check
00:33:33.690 00:33:33.700 this one up here see that large the one
00:33:35.880 00:33:35.890 easy to get to on the edge of the board
00:33:37.470 00:33:37.480 I think you can see that okay hopefully
00:33:41.790 00:33:41.800 it'll make a good connection
00:33:52.390 00:33:52.400 we could also you can also go into this
00:33:55.430 00:33:55.440 meter and we can hold it down and go in
00:33:59.240 00:33:59.250 and set up new keep hitting the button
00:34:06.350 00:34:06.360 until we come down to ESR capacitor plus
00:34:10.010 00:34:10.020 yes yes all right so one in three though
00:34:12.710 00:34:12.720 I may have to change my hold it down I
00:34:16.180 00:34:16.190 think I'll have to change mine I got it
00:34:20.899 00:34:20.909 on one and two
00:34:36.520 00:34:36.530 so if you can see that when it's on this
00:34:40.629 00:34:40.639 mode you can actually just clip it to
00:34:43.210 00:34:43.220 something it actually itself like out of
00:34:48.220 00:34:48.230 the tech did you will except detect
00:34:51.450 00:34:51.460 start showing the capacitance and this
00:34:54.700 00:34:54.710 series resistance on the screen so that
00:34:57.820 00:34:57.830 way you can do it hands-free hope you
00:35:01.120 00:35:01.130 can see this on camera sorry
00:35:06.640 00:35:06.650 there we go we've got 48 micro farad and
00:35:10.710 00:35:10.720 point 0.99 2.0 point 9 8 ohms and this
00:35:21.970 00:35:21.980 is a 47 micro farad can you see that
00:35:24.609 00:35:24.619 okay no it's a 47 micro farad as 63
00:35:33.549 00:35:33.559 votes
00:35:36.420 00:35:36.430 it's the 85 c rated capacitor so it's
00:35:40.539 00:35:40.549 not the highest quality or high seen
00:35:43.240 00:35:43.250 capacitor for example this one I didn't
00:35:46.359 00:35:46.369 mention that but this one is 105 see
00:35:48.870 00:35:48.880 it's right on the top there 105 C
00:35:52.740 00:35:52.750 typically you higher switching capacity
00:35:57.279 00:35:57.289 and like lower ESR capacitors are rated
00:36:01.289 00:36:01.299 for that higher temperature we got one
00:36:04.180 00:36:04.190 more here to check in circuit
00:36:15.260 00:36:15.270 eighty two hundred microfarad at fifty
00:36:18.450 00:36:18.460 working votes and is showing 8.15
00:36:25.590 00:36:25.600 military or 8150 microfarad at point
00:36:31.800 00:36:31.810 zero eight or point one on I typically
00:36:41.160 00:36:41.170 used as if socket on nine percent of the
00:36:43.290 00:36:43.300 test if I can on this on this meter so
00:36:46.260 00:36:46.270 something some of this a plug right in
00:36:49.520 00:36:49.530 but I mention in the previous video
00:36:51.720 00:36:51.730 about this that you can you can solder
00:36:53.850 00:36:53.860 your own leads only get a better
00:36:55.110 00:36:55.120 connection or and even even going
00:36:58.950 00:36:58.960 through the calibration whether we're
00:37:00.870 00:37:00.880 the lead on there and actually getting
00:37:03.180 00:37:03.190 it closer to zero if it's way off on you
00:37:05.460 00:37:05.470 point zero seven wasn't a big deal for
00:37:07.560 00:37:07.570 me this time I just wrote it down and
00:37:09.900 00:37:09.910 I'll subtract that accordingly but
00:37:11.510 00:37:11.520 either way you can do it either way it
00:37:13.920 00:37:13.930 actually work quite well going up in
00:37:18.450 00:37:18.460 there just the order of expense will go
00:37:20.760 00:37:20.770 to this little end me up mes are one
00:37:24.600 00:37:24.610 hundred just a straight ESR meter so
00:37:30.480 00:37:30.490 we'll cut this on make sure the displace
00:37:32.820 00:37:32.830 shows up okay on camera I believe it's
00:37:36.870 00:37:36.880 better down and up I think the glare is
00:37:40.620 00:37:40.630 worse the way my lighting is we'll bring
00:37:44.850 00:37:44.860 in the big twenty two hundred check it
00:37:52.849 00:37:52.859 and it auto ranges to the 0 to 1 ohm
00:37:55.969 00:37:55.979 range and shows point zero one owns and
00:38:01.009 00:38:01.019 it tells you just good for a cat with
00:38:03.440 00:38:03.450 Louis yes our but it's referencing a
00:38:06.589 00:38:06.599 twenty five boat let your let it cap so
00:38:10.160 00:38:10.170 that's the only thing is you got to
00:38:12.140 00:38:12.150 watch what it's referencing just because
00:38:13.819 00:38:13.829 it says good it may not always be good
00:38:18.940 00:38:18.950 one thing I failed to do was the I meant
00:38:22.999 00:38:23.009 to show you the zero first which is
00:38:26.779 00:38:26.789 still dead I open earlier when I did it
00:38:28.549 00:38:28.559 on the video we'll go through and check
00:38:32.989 00:38:32.999 the 5560 microfarad it's showing good
00:38:40.999 00:38:41.009 point zero two seven will go to the one
00:38:50.029 00:38:50.039 that's the null failed capacitor and it
00:38:58.910 00:38:58.920 shows you know from that from the 10 to
00:39:01.430 00:39:01.440 100 ranges over range overload it's
00:39:05.630 00:39:05.640 actually um showing that it it can't
00:39:08.269 00:39:08.279 even read it it said it was a reading
00:39:11.660 00:39:11.670 his overflow so letting you know
00:39:13.759 00:39:13.769 something is definitely going on there
00:39:15.199 00:39:15.209 didn't pick up a circuit at all
00:39:25.190 00:39:25.200 point zero 100 point zero one six
00:39:29.690 00:39:29.700 showing that it's good I didn't have a
00:39:33.060 00:39:33.070 good connection on that one actually
00:39:34.350 00:39:34.360 your next song on the camera moving
00:39:36.390 00:39:36.400 before I did good in circuit will bring
00:39:51.180 00:39:51.190 this board back in with a 2700 shorted
00:39:58.530 00:39:58.540 leaves can be a little challenging but
00:40:00.740 00:40:00.750 like I say in the long run especially
00:40:02.940 00:40:02.950 the hundred kilohertz you want to be as
00:40:05.760 00:40:05.770 short as possible it's showing good
00:40:12.860 00:40:12.870 we'll go ahead and check this little one
00:40:15.240 00:40:15.250 like we did with the 328 small when
00:40:23.220 00:40:23.230 you're gonna show a higher resistance
00:40:29.750 00:40:29.760 Oh point five for one
00:40:37.730 00:40:37.740 and then we also did this on the 328
00:40:54.220 00:40:54.230 and the showing point zero one
00:41:04.720 00:41:04.730 you know overall this meters quick and
00:41:07.000 00:41:07.010 handy it does a good job and the one
00:41:09.280 00:41:09.290 thing you may have already noticed just
00:41:10.870 00:41:10.880 a problem to me with this meter I knew
00:41:13.450 00:41:13.460 it when I bought it that it was simply a
00:41:15.100 00:41:15.110 TSR meter but for the money it wasn't a
00:41:18.040 00:41:18.050 bad a bad deal it's not a bad little
00:41:20.170 00:41:20.180 meter but you can buy the capacitance
00:41:23.380 00:41:23.390 meter all the ESR meter I do prefer to
00:41:25.990 00:41:26.000 have them both in one because it really
00:41:27.790 00:41:27.800 does matter you looking for most of dead
00:41:29.710 00:41:29.720 short but if you kept if you capacitor
00:41:31.750 00:41:31.760 is shorted it can almost show goods and
00:41:34.600 00:41:34.610 you got to really watch that I really
00:41:37.270 00:41:37.280 learned over the years I really like I
00:41:39.210 00:41:39.220 like one they were fixing to come to
00:41:42.010 00:41:42.020 next that shows the capacitance and the
00:41:45.720 00:41:45.730 ESR together all the rest of them here
00:41:49.270 00:41:49.280 today do they do just that so we get
00:41:53.620 00:41:53.630 into one of my favorites here the little
00:41:57.280 00:41:57.290 peak go ahead and hook it up one thing
00:42:03.310 00:42:03.320 about this peak is this it's really it's
00:42:05.920 00:42:05.930 also hands off once you cut this on get
00:42:08.770 00:42:08.780 a show analyzing either read the
00:42:12.310 00:42:12.320 capacitor it usually give you a SR
00:42:14.890 00:42:14.900 before it even has time to fully rise on
00:42:18.580 00:42:18.590 a large capacitor depending on the value
00:42:20.500 00:42:20.510 it's going to take a little longer but I
00:42:22.290 00:42:22.300 mean right off the bat is quick nineteen
00:42:25.060 00:42:25.070 fifty eight point zero two actually
00:42:29.320 00:42:29.330 shows the capacitance spec
00:42:42.500 00:42:42.510 point zero 6 ohms see if it'll pick up
00:42:50.069 00:42:50.079 the bad one a open circuit or low
00:42:56.460 00:42:56.470 capacitance think it's both
00:43:21.890 00:43:21.900 took a while this is the high value
00:43:24.110 00:43:24.120 capacitor point zero five on for me it's
00:43:28.850 00:43:28.860 a big help to show the capacitance value
00:43:30.590 00:43:30.600 on screen without having to go back and
00:43:34.760 00:43:34.770 check them when you have a low low ohms
00:43:37.040 00:43:37.050 reading here we go to 2700
00:43:48.610 00:43:48.620 point zero one 24:46 I can do the little
00:43:58.720 00:43:58.730 one on this one too I forgot and these
00:44:02.440 00:44:02.450 these low alligator clips do grab good
00:44:04.630 00:44:04.640 on these leads even on on the board I
00:44:07.720 00:44:07.730 can let them go in point six six fifty
00:44:11.860 00:44:11.870 one like a very good deal last but not
00:44:17.260 00:44:17.270 least since we are doing a comparison
00:44:23.160 00:44:23.170 try to do them all it's already ten ones
00:44:28.630 00:44:28.640 point zero two on the es are seventy
00:44:34.510 00:44:34.520 nine sixty two and being an in circuit
00:44:39.760 00:44:39.770 test where did it quick all right well
00:44:47.830 00:44:47.840 this by far one of my favorites so far
00:44:53.130 00:44:53.140 but next we bring in the high dollar job
00:44:55.900 00:44:55.910 and surely it's better
00:44:58.510 00:44:58.520 well maybe I'm gonna try to make this as
00:45:04.690 00:45:04.700 quick and painless as possible because
00:45:07.360 00:45:07.370 it's this meter here has a lot to it so
00:45:11.020 00:45:11.030 I want you to see the features of it and
00:45:13.900 00:45:13.910 compare it with the ESR reading of the
00:45:17.140 00:45:17.150 other meters we had the day but I guess
00:45:19.780 00:45:19.790 it's it's so feature-rich that it can be
00:45:24.670 00:45:24.680 a little bit time-consuming to explain a
00:45:26.950 00:45:26.960 lot of the functions of it but one thing
00:45:29.320 00:45:29.330 we are talked about is the different
00:45:30.850 00:45:30.860 frequencies the paralleled a series
00:45:32.890 00:45:32.900 checking so just to mention that the
00:45:38.740 00:45:38.750 book tells you it defaults to parallel
00:45:42.070 00:45:42.080 on the reading photo for the ESR and it
00:45:48.280 00:45:48.290 says in capacitance both it reads both
00:45:50.800 00:45:50.810 you can have a submenu so you got you
00:45:53.140 00:45:53.150 got the main and then the secondary
00:45:55.560 00:45:55.570 display so we have capacitance and then
00:45:58.690 00:45:58.700 we'll have the ESR up top and
00:46:01.040 00:46:01.050 smaller font but it defaults to parallel
00:46:07.400 00:46:07.410 and you'll see PA are on the screen and
00:46:09.830 00:46:09.840 then if you hold it down and go to serie
00:46:12.080 00:46:12.090 series they recommend series for more of
00:46:15.590 00:46:15.600 inductance and they recommend the
00:46:18.650 00:46:18.660 parallel for capacitance and resistance
00:46:20.270 00:46:20.280 so just checking out a circuit you would
00:46:23.300 00:46:23.310 think you would definitely use a
00:46:24.350 00:46:24.360 parallel but you kind of gotta play
00:46:27.110 00:46:27.120 around with it and see what works the
00:46:28.550 00:46:28.560 best and also they recommend anything
00:46:32.810 00:46:32.820 that's less than point zero 1 microfarad
00:46:35.390 00:46:35.400 which we don't have anything like that
00:46:36.920 00:46:36.930 today they like use 1 kilohertz signal
00:46:41.990 00:46:42.000 to check it but they're actually saying
00:46:44.990 00:46:45.000 anything greater than 10 microfarad to
00:46:47.840 00:46:47.850 use 120 Hertz which is a little bit odd
00:46:51.770 00:46:51.780 as we mentioned earlier but all the rest
00:46:55.850 00:46:55.860 of these meters well it with the
00:47:00.170 00:47:00.180 exception of this one uses 100 kilohertz
00:47:02.710 00:47:02.720 so and that that's typical of it yes our
00:47:08.240 00:47:08.250 meter is they use 100 kilohertz because
00:47:10.550 00:47:10.560 I think that's what the factory of most
00:47:13.250 00:47:13.260 capacitor is right there and based their
00:47:15.770 00:47:15.780 ratings and specs of capacitors on so
00:47:20.660 00:47:20.670 we're getting into this one will cut it
00:47:23.180 00:47:23.190 on do it a capacitance what's already on
00:47:29.380 00:47:29.390 capacitance and we'll go to ESR
00:47:37.530 00:47:37.540 we're short out the leads and do a check
00:47:44.900 00:47:44.910 actually let me see what frequency this
00:47:47.280 00:47:47.290 is on one kilohertz but let's go to the
00:47:51.660 00:47:51.670 100 or 120 kilohertz me 1 120 Hertz I'm
00:47:55.530 00:47:55.540 sorry
00:47:56.570 00:47:56.580 and then let's let's go to let's leave
00:47:59.820 00:47:59.830 it on parallel that's what they kind of
00:48:01.470 00:48:01.480 recommend for checking in our range and
00:48:04.880 00:48:04.890 we will take these little leads and
00:48:37.329 00:48:37.339 okay
00:48:40.359 00:48:40.369 there we go
00:48:46.120 00:48:46.130 turn this to the right polarity
00:48:59.440 00:48:59.450 and he's showing 1.88 military to 1880
00:49:05.579 00:49:05.589 microfarad so but the ESR is point zero
00:49:11.170 00:49:11.180 three nine or so actually showing like
00:49:14.079 00:49:14.089 this capacitor maybe just a little bit
00:49:16.690 00:49:16.700 out of Tolerance on the on the ESR but
00:49:20.230 00:49:20.240 now that the peak actually showed it to
00:49:22.120 00:49:22.130 be within tolerance
00:49:31.760 00:49:31.770 without looking does that expects up of
00:49:34.190 00:49:34.200 that when it's really close to the
00:49:35.420 00:49:35.430 tolerance
00:49:46.759 00:49:46.769 5:06 and point zero eight six showing
00:49:55.470 00:49:55.480 just a little bit out also what I'm
00:49:58.620 00:49:58.630 going to show now before I go much
00:50:00.180 00:50:00.190 further I'm going to show the difference
00:50:01.650 00:50:01.660 in the series hold it down and go to the
00:50:04.109 00:50:04.119 series
00:50:12.440 00:50:12.450 you
00:50:42.390 00:50:42.400 0-3
00:50:49.470 00:50:49.480 I know some of them I shared a good bit
00:50:52.230 00:50:52.240 different being his series than it did
00:50:55.410 00:50:55.420 parallel once he wrote a let's check the
00:51:06.930 00:51:06.940 backup a sitter with it
00:51:15.740 00:51:15.750 sheron's attend an affair it's an
00:51:19.350 00:51:19.360 absolutely no reading of ohms on its
00:51:22.170 00:51:22.180 scale so definitely picked up the back
00:51:25.110 00:51:25.120 of Pastor that's every one of them we
00:51:26.970 00:51:26.980 try the day did pick up the bad one I
00:51:28.950 00:51:28.960 wish I had more bad ones still around I
00:51:31.560 00:51:31.570 usually toss them I don't really think
00:51:33.000 00:51:33.010 about saving them point zero to six or
00:51:42.210 00:51:42.220 seven point three million let's try some
00:51:51.000 00:51:51.010 in circuit
00:51:51.870 00:51:51.880 here's that 2700 think it doesn't matter
00:51:56.490 00:51:56.500 about polarity
00:52:11.660 00:52:11.670 two point three four five million point
00:52:15.559 00:52:15.569 zero one eight five ohms shows good
00:52:26.560 00:52:26.570 I grabbed pretty good my quiet you know
00:52:34.960 00:52:34.970 say there it goes
00:52:41.640 00:52:41.650 almost 46 45.6 microfarad what 1.65
00:52:46.920 00:52:46.930 that's good and last but not least
00:53:12.890 00:53:12.900 he's showing 7.39 Milly 0.036 that was
00:53:19.400 00:53:19.410 good
00:53:26.800 00:53:26.810 so summing things up every meter here
00:53:30.580 00:53:30.590 from the least expensive less than $20
00:53:33.330 00:53:33.340 category up to the 250 to $300 category
00:53:39.660 00:53:39.670 every meter here ESR wise actually
00:53:43.960 00:53:43.970 checked in circuit and out of circuit
00:53:46.300 00:53:46.310 capacitors relatively across the board
00:53:50.350 00:53:50.360 the same as far as a pass and failed
00:53:52.330 00:53:52.340 American measure this one only checks
00:53:57.100 00:53:57.110 ESR but still they found the only known
00:54:00.580 00:54:00.590 bad one they showed us the ones that
00:54:03.820 00:54:03.830 were on the fence kind of borderline but
00:54:05.830 00:54:05.840 they all the hour showed that it was
00:54:07.270 00:54:07.280 about borderline which on the higher
00:54:11.860 00:54:11.870 range of things that does get very low
00:54:14.610 00:54:14.620 so this is price-wise if I were to maybe
00:54:23.980 00:54:23.990 rearrange these to being the most the
00:54:26.530 00:54:26.540 most useful maybe the most useful the
00:54:30.460 00:54:30.470 easiest the ease of use and the most
00:54:33.430 00:54:33.440 reliability and quick of testing will
00:54:37.630 00:54:37.640 probably probably still being this this
00:54:41.950 00:54:41.960 order I mean both of these are made
00:54:45.760 00:54:45.770 where and this one as well just checking
00:54:49.870 00:54:49.880 yeah ESR wise this one is just as easy
00:54:52.360 00:54:52.370 as any of them but checking these are
00:54:54.850 00:54:54.860 checking but just the fact that it's on
00:54:57.370 00:54:57.380 the ESR meter don't show capacitance as
00:54:59.980 00:54:59.990 well while you're testing for that
00:55:02.110 00:55:02.120 region that's always gonna rank a little
00:55:03.730 00:55:03.740 low this one has such a high-end use for
00:55:08.590 00:55:08.600 other things but just for strictly boy
00:55:11.830 00:55:11.840 checking electrolytic caps switch mode
00:55:15.040 00:55:15.050 power supplies and things of that nature
00:55:16.510 00:55:16.520 where you're just looking for the ESR I
00:55:19.080 00:55:19.090 really don't go to this one that often
00:55:21.160 00:55:21.170 it's a little bit tedious you have to
00:55:24.010 00:55:24.020 play with the frequency and where this
00:55:25.650 00:55:25.660 parallel and series and these here just
00:55:28.030 00:55:28.040 work so this is really my go-to I really
00:55:32.200 00:55:32.210 like the look peak it works well the
00:55:34.660 00:55:34.670 leads are nice the clips are good on it
00:55:37.800 00:55:37.810 00:55:39.380 00:55:39.390 I just talked about the good things
00:55:42.140 00:55:42.150 about it for a second the auto discharge
00:55:44.359 00:55:44.369 is really neat about it because in
00:55:46.519 00:55:46.529 circuit where there has a bleed resistor
00:55:48.500 00:55:48.510 or not it does a good job don't the only
00:55:51.890 00:55:51.900 negative thing about this one is it does
00:55:53.750 00:55:53.760 take the little twelve volt the 23 a
00:55:57.019 00:55:57.029 series a little bit a little bit harder
00:56:00.079 00:56:00.089 they get into with the three screws but
00:56:01.640 00:56:01.650 not a big deal not quite as easy as the
00:56:04.160 00:56:04.170 rest of these to replace which you know
00:56:07.009 00:56:07.019 they all have some type of battery door
00:56:09.559 00:56:09.569 when I swing a screw but with that said
00:56:15.650 00:56:15.660 this being the 60 to 70 being a better
00:56:18.289 00:56:18.299 version with more features the the specs
00:56:22.549 00:56:22.559 on the CSR 70 actually state that it's a
00:56:26.569 00:56:26.579 triple-a battery if that's correct then
00:56:28.220 00:56:28.230 the triple-a battery would be a lot a
00:56:30.410 00:56:30.420 lot easier to come by I do keep some 12
00:56:33.500 00:56:33.510 volts around for the source no big deal
00:56:34.970 00:56:34.980 to me that's about the only negative
00:56:37.370 00:56:37.380 thing I got for the for the whole thing
00:56:39.680 00:56:39.690 and it's naive an issue with the 70
00:56:41.240 00:56:41.250 series the SR 70 mile this one again
00:56:46.190 00:56:46.200 just rank really high good little meter
00:56:48.769 00:56:48.779 for the money great to have around well
00:56:50.690 00:56:50.700 worth it this one for the money
00:56:53.150 00:56:53.160 I think it's fifty five bucks not not
00:56:54.829 00:56:54.839 bad just about if I had my choice I
00:56:58.069 00:56:58.079 would always have like it's like a
00:56:59.329 00:56:59.339 passing it showing this one pretty much
00:57:01.910 00:57:01.920 do it all yes kind of a painting a
00:57:05.120 00:57:05.130 thesis to set up and get ready but it
00:57:07.970 00:57:07.980 does have a lot of features I didn't
00:57:09.589 00:57:09.599 talk about like to record the USB so you
00:57:14.359 00:57:14.369 can hook it to the PC for checking
00:57:16.099 00:57:16.109 charting a lot of features in this one
00:57:18.200 00:57:18.210 that we just don't need for this test so
00:57:24.249 00:57:24.259 with that being said I hope I hope these
00:57:27.289 00:57:27.299 four meters comparing gives you a little
00:57:29.539 00:57:29.549 insight of the of the ESR checks and and
00:57:33.380 00:57:33.390 maybe something to look for if you're
00:57:34.910 00:57:34.920 interested in buying a meter or maybe
00:57:36.799 00:57:36.809 you already have one looking to buy
00:57:38.240 00:57:38.250 another one hopefully got a little bit
00:57:40.880 00:57:40.890 out of this video today if you liked it
00:57:43.309 00:57:43.319 please give it a thumbs up if you got
00:57:45.410 00:57:45.420 any comments good or bad please leave
