00:00:04.240 hello welcome back to thrifty to share 00:00:07.70900:00:07.719 today I thought we'd look at capacitors 00:00:10.78000:00:10.790 some of the safety features of 00:00:13.50900:00:13.519 capacitors as far as discharging them 00:00:15.40000:00:15.410 checking the ESR or equivalent series 00:00:18.67000:00:18.680 resistance of capacitors since it's very 00:00:22.12000:00:22.130 important in the circuit especially some 00:00:24.09900:00:24.109 power supplies high frequency 00:00:26.93900:00:26.949 applications we're gonna start off 00:00:29.43900:00:29.449 looking at the yo sodium 328 today I did 00:00:37.00000:00:37.010 a full review of this in one of my 00:00:40.68900:00:40.699 previous videos if you haven't seen it 00:00:42.61000:00:42.620 you might want to look at it or at least 00:00:44.35000:00:44.360 parts of it sums up a lot of the 00:00:46.14900:00:46.159 operation I'm not gonna go over in 00:00:47.89000:00:47.900 detail today but I'm gonna use it for 00:00:52.39000:00:52.400 comparison I also have a little science 00:00:57.25000:00:57.260 tech the NES are 100 mister version one 00:01:02.22900:01:02.239 not the version two but I haven't been 00:01:04.81000:01:04.820 real long version two is a little better 00:01:47.16000:01:47.170 start off with a quick look at the GM 00:01:50.44000:01:50.450 328 I won't bore you with the details of 00:01:54.21900:01:54.229 this one since I've already done a 00:01:55.84000:01:55.850 comprehensive video a lot of the 00:01:58.33000:01:58.340 functionality that I figured out about 00:02:00.73000:02:00.740 it so it doesn't come with a lot of 00:02:03.25000:02:03.260 literature pretty much comes in the box 00:02:06.16000:02:06.170 like it is without the backplate I have 00:02:08.44000:02:08.450 that as I mentioned on the video but it 00:02:11.55900:02:11.569 doesn't do a really good job with 00:02:12.85000:02:12.860 capacitance in the air saw so I won't 00:02:15.04000:02:15.050 included and 00:02:16.09000:02:16.100 test today it's over you look of the 00:02:19.54000:02:19.550 meter today unless science tech mes are 00:02:28.21000:02:28.220 100 this is the version one they got the 00:02:30.76000:02:30.770 version two out now comes a little um 00:02:41.35000:02:41.360 manual shows a bit use 100 kilohertz for 00:02:47.56000:02:47.570 testing 00:02:58.63000:02:58.640 it does have a backlight it's pretty 00:03:02.11000:03:02.120 decent 00:03:06.44000:03:06.450 this one also has a backlight which I I 00:03:09.26000:03:09.270 didn't mention because it's actually 00:03:10.75900:03:10.769 pretty nice back 00:03:24.30900:03:24.319 the leash together 00:03:39.38000:03:39.390 so we'll let you know the range innocent 00:03:41.69000:03:41.700 auto and the ESR value whether it's good 00:03:47.14000:03:47.150 for for 25 volt rated reference and also 00:03:52.61000:03:52.620 gives you a comparison chart below which 00:03:54.71000:03:54.720 is pretty handy to have right on the 00:03:58.37000:03:58.380 meter a lot of those charts are generic 00:04:00.74000:04:00.750 you'd have to look at the caps 00:04:02.03000:04:02.040 information directly yeah you would have 00:04:05.66000:04:05.670 to just look at the like the spec for 00:04:08.36000:04:08.370 the capacitor manufacturers so where the 00:04:12.11000:04:12.120 B Rubicon or you'd have to get the 00:04:15.02000:04:15.030 information off actual captain look up 00:04:18.71000:04:18.720 the data on the datasheet a reference 00:04:21.56000:04:21.570 sheet on the cap itself because yes our 00:04:23.99000:04:24.000 values do do different from manufacturer 00:04:26.90000:04:26.910 or even they're a series of caps because 00:04:30.49000:04:30.500 some capacitors are are very good low at 00:04:34.79000:04:34.800 low ESR capacitors especially for higher 00:04:38.03000:04:38.040 in applications and how high frequency 00:04:44.57000:04:44.580 applications should I say the manual is 00:04:47.65900:04:47.669 really good with the atlas ESR sixty an 00:04:59.48000:04:59.490 already cut it on here by accident 00:05:01.87000:05:01.880 it's okay this was the only one that we 00:05:07.64000:05:07.650 had that does not have a backlight but I 00:05:09.74000:05:09.750 can honestly say that I never really 00:05:11.84000:05:11.850 needed this got a really nice bright 00:05:13.61000:05:13.620 green I'm back into the LCD so never 00:05:21.08000:05:21.090 really needed it 00:05:27.48000:05:27.490 and the resistance measurements always 00:05:30.55000:05:30.560 pretty accurate with this one it does 00:05:36.12900:05:36.139 like I say capacitance and the 00:05:37.99000:05:38.000 equivalent series resistance and last 00:05:43.33000:05:43.340 but not least the BK precision comes 00:05:50.14000:05:50.150 with the leaves the meter a USB cable 00:05:54.39900:05:54.409 and this one will communicate with a PC 00:05:57.58000:05:57.590 based the driver you can download from 00:06:00.01000:06:00.020 the internet also comes with an AC 00:06:02.74000:06:02.750 adapter so you're not just relying on 00:06:09.18900:06:09.199 the battery on the beach testing a lock 00:06:11.70000:06:11.710 that's kind of Handy to mention a little 00:06:15.99900:06:16.009 bit about price here I have them in 00:06:18.07000:06:18.080 order from least to the most expensive 00:06:22.86000:06:22.870 as of right now Amazon you can get the 00:06:26.55000:06:26.560 GM 328 for under $20 19:49 was the last 00:06:31.64900:06:31.659 price that i i've seen on it 00:06:35.76000:06:35.770 the mes are 100 comes in a lot of 00:06:40.14900:06:40.159 different name brands this one science 00:06:42.93900:06:42.949 tech it's at least a lot of them looks 00:06:44.62000:06:44.630 similar packaging even even down to the 00:06:48.20900:06:48.219 the chart table yes our table on the 00:06:51.60000:06:51.610 front of the meter but like they version 00:06:56.05000:06:56.060 2 is available now with a little more 00:06:57.73000:06:57.740 features with around $55 to go on price 00:07:01.24000:07:01.250 on these it does have the hundred 00:07:03.99900:07:04.009 kilohertz to hit remove the impedance 00:07:07.45000:07:07.460 off the capacitor when checking the ESR 00:07:10.92000:07:10.930 it also uses the square wave now that 00:07:16.36000:07:16.370 they say the diversion to uses a sine 00:07:18.73000:07:18.740 wave to give a a little bit better 00:07:21.89900:07:21.909 testing its supposed to have a 00:07:25.65900:07:25.669 resolution down the point 0 0 1 ohm it 00:07:30.39900:07:30.409 does the idle display for the bad caps a 00:07:32.43900:07:32.449 good cat based on a common 25 00:07:36.46900:07:36.479 electrolytic cap this one uses a nine 00:07:39.79900:07:39.809 vote but the the version two uses two 00:07:42.43900:07:42.449 doublea's and I think the version 2 can 00:07:46.61000:07:46.620 also be USB power which this one has it 00:07:49.04000:07:49.050 as well the pts are 60 is actually 00:07:58.92900:07:58.939 becoming obsolete now they had the 70 00:08:01.96900:08:01.979 model out which looks almost identical 00:08:04.73000:08:04.740 but this one sells for about 119 if you 00:08:10.90900:08:10.919 can still find it I believe the 90 of 00:08:13.48900:08:13.499 the ESR 70 is still selling for about 00:08:17.54000:08:17.550 the same price like I said with a little 00:08:20.39000:08:20.400 bit better features on the 879 be it's 00:08:28.82000:08:28.830 selling for about $2.99 00:08:31.42900:08:31.439 I think Amazon has it for maybe 263 but 00:08:38.81000:08:38.820 it's by far the most expensive but I 00:08:45.37900:08:45.389 won't really get into the complete 00:08:49.69900:08:49.709 comparison of it because or review of it 00:08:53.12000:08:53.130 even because it's the LCR meter and has 00:08:55.30900:08:55.319 a lot more functionality than what we're 00:08:57.29000:08:57.300 going to get into today just checking I 00:08:59.44900:08:59.459 just want to stick with Strictly 00:09:01.06900:09:01.079 capacitance and and yes all on ESR meter 00:09:05.31900:09:05.329 but checking things like switch mode 00:09:07.67000:09:07.680 power supplies and know the high 00:09:09.25900:09:09.269 frequency applications ESR is very 00:09:11.99000:09:12.000 important and it's a easy check 00:09:13.62900:09:13.639 sometimes if it's borderline I don't so 00:09:16.40000:09:16.410 much worry about a cap but this is one 00:09:20.62900:09:20.639 of the better charts I've seen and I use 00:09:22.55000:09:22.560 it a lot to go by and I didn't realize 00:09:25.57900:09:25.589 it till I bought the the peak that this 00:09:28.63900:09:28.649 like this charts actually in the booklet 00:09:31.30000:09:31.310 whether they originated or not I just 00:09:33.71000:09:33.720 use this generic chart I don't know but 00:09:36.74000:09:36.750 it's the exact same chart and wording in 00:09:40.00900:09:40.019 the actual book that comes with the 00:09:41.62900:09:41.639 atlas yes or 00:09:46.77000:09:46.780 so a little bit of quick rundown of 00:09:51.18000:09:51.190 course this one has already been 00:09:54.82000:09:54.830 mentioned that the video previous video 00:09:57.85000:09:57.860 on this one already tells a lot of 00:09:59.29000:09:59.300 detail about it I'll go into this peak 00:10:03.31000:10:03.320 because it has a lot of features as far 00:10:05.77000:10:05.780 as the 100 kilohertz capacitance and 00:10:08.98000:10:08.990 equivalent series resistance check it's 00:10:11.44000:10:11.450 got the automatic discharge which is 00:10:13.51000:10:13.520 this is the only one that actually has 00:10:15.49000:10:15.500 that but it does ask that it's less than 00:10:19.21000:10:19.220 50 volts if the capacitor is greater 00:10:21.70000:10:21.710 than 50 volts then it will let you know 00:10:24.79000:10:24.800 on the screen on the atom on the 00:10:27.55000:10:27.560 automatic analysis and let you know that 00:10:30.90000:10:30.910 capacitor is greater than 50 volts I 00:10:33.76000:10:33.770 will show you the voltage read on the 00:10:35.65000:10:35.660 screen and it will ask you to discharge 00:10:37.69000:10:37.700 it properly the leads on this little 00:10:41.08000:10:41.090 meter are very good even though it's a 00:10:45.25000:10:45.260 little bit of a specialty you can get 00:10:48.07000:10:48.080 replacement clips and it looks to be 00:10:50.95000:10:50.960 gold-plated and whenever you short these 00:10:56.68000:10:56.690 out and do a check it always shows zero 00:10:59.17000:10:59.180 I mean if it really does a good job on 00:11:01.33000:11:01.340 the low home scale on the 60 the maximum 00:11:07.45000:11:07.460 resistance had to do is 20 ohms now the 00:11:10.18000:11:10.190 70 is 40 ohms so the one that's 00:11:14.05000:11:14.060 available now we'll go to 40 ohms and 00:11:18.18000:11:18.190 just to mention the 60 don't have the 00:11:20.83000:11:20.840 auto boy alerts the 70 has Auto boiler 00:11:23.83000:11:23.840 to let you know and I thought that was 00:11:26.71000:11:26.720 gonna that would be a really neat 00:11:28.24000:11:28.250 feature 00:11:28.80000:11:28.810 if I were I'm gonna save and I think 00:11:31.51000:11:31.520 I'll enjoy that because just going 00:11:33.79000:11:33.800 through checking maybe on a circuit 00:11:36.76000:11:36.770 board just going through checking 00:11:38.98000:11:38.990 different caps it'll actually have a 00:11:41.11000:11:41.120 different tone of what range the ESR is 00:11:44.95000:11:44.960 so you can possibly go across the 00:11:47.38000:11:47.390 circuit board and not even have to look 00:11:49.60000:11:49.610 back up until you hear a different tone 00:11:52.03000:11:52.040 or beep well maybe you don't hear 00:11:54.04000:11:54.050 anything at all like it's not reading 00:11:56.07900:11:56.089 anything 00:11:56.93000:11:56.940 so I think that's a really good feature 00:11:59.71000:11:59.720 that capacity range on this one is one 00:12:02.48000:12:02.490 microfarad to 22,000 and it does really 00:12:06.92000:12:06.930 good for capacitance and low home checks 00:12:08.99000:12:09.000 which actually all these ESR means to do 00:12:12.02000:12:12.030 that it does have the auto power off it 00:12:17.18000:12:17.190 does take a little 12 volt alkaline 00:12:19.18000:12:19.190 batteries of the 23:23 a type and it is 00:12:30.26000:12:30.270 polarity free this one and the GM 328 or 00:12:36.50000:12:36.510 polarity free you just plug it up or 00:12:38.42000:12:38.430 hook it up to the capacitor either way 00:12:40.73000:12:40.740 you get a reef properly these two 00:12:44.78000:12:44.790 actually want you to do the polarity 00:12:46.46000:12:46.470 correctly on these as far as the 879 be 00:12:57.10000:12:57.110 it has a lot of configure you know 00:13:00.17000:13:00.180 configurable capabilities 00:13:01.82000:13:01.830 you know from beep out of all the fault 00:13:04.13000:13:04.140 modes that it comes on to it also has 00:13:07.70000:13:07.710 the backlight the LCDs really good on 00:13:09.92000:13:09.930 this meter the case is really good 00:13:13.91000:13:13.920 quality I do I do read the light became 00:13:19.36000:13:19.370 stuff I got a little meter here I know 00:13:23.72000:13:23.730 it's a different subject but they make 00:13:25.55000:13:25.560 similar things I like a little two kids 00:13:27.82000:13:27.830 they look 2709 be he's got the little 00:13:32.30000:13:32.310 magnetic hanger and I just kind of keep 00:13:35.39000:13:35.400 hanging up on my Beach it's the one I 00:13:37.76000:13:37.770 have my tweezers hook to for some of the 00:13:40.58000:13:40.590 circuit board probing it's a good little 00:13:43.37000:13:43.380 eater it's a true RMS I have no issues 00:13:45.59000:13:45.600 with it 00:13:46.04000:13:46.050 this meters may be very similar as far 00:13:48.65000:13:48.660 as the case it has the USB capability to 00:13:53.54000:13:53.550 download the driver it can be powered by 00:13:56.33000:13:56.340 the wall adapter and it's takes the 00:14:00.38000:14:00.390 generally test like the 1 kilohertz test 00:14:05.09000:14:05.100 for 4.0 1 microfarad are smaller and 00:14:08.84000:14:08.850 when you get above 10 00:14:10.31000:14:10.320 microfarad it wants you to use the lower 00:14:12.20000:14:12.210 like 120 Hertz frequency which seems a 00:14:16.01000:14:16.020 little unusual to me I know that 00:14:17.75000:14:17.760 typically 100 kilohertz is what 00:14:19.82000:14:19.830 manufacturers test their ESR that's a 00:14:24.68000:14:24.690 typical thing not across the board but 00:14:27.64000:14:27.650 you can also select besides the 00:14:31.34000:14:31.350 frequency selection you can you can 00:14:33.53000:14:33.540 check and change this one only goes up 00:14:39.08000:14:39.090 at 10 kilohertz from 100 Hertz and it 00:14:42.86000:14:42.870 steps up to 10 kilohertz this one like I 00:14:45.65000:14:45.660 said does not do 100 kilohertz the the 00:14:48.89000:14:48.900 880 model that they make will but I 00:14:51.68000:14:51.690 think just 399 so to meet us a lot of 00:14:56.42000:14:56.430 money for 4 meter but somebody uses it 00:14:59.63000:14:59.640 every day they have that much 00:15:02.48000:15:02.490 functionality it's probably worth it it 00:15:06.47000:15:06.480 defaults on powerup it defaults to 00:15:13.25000:15:13.260 parallel and 1 kilohertz for the check 00:15:22.04000:15:22.050 we can hold this button down from P to s 00:15:26.57000:15:26.580 and go to SC off or series and we can go 00:15:31.34000:15:31.350 frequency up one to ten and to go down 00:15:34.57900:15:34.589 to a hundred 100 Hertz one twenty one 00:15:38.00000:15:38.010 kilohertz ten think he'll Hertz so this 00:15:42.88900:15:42.899 one has a lot of functionality a lot of 00:15:44.84000:15:44.850 different ways to check yes alright 00:15:48.94900:15:48.959 capacitance values which sometimes can 00:15:51.56000:15:51.570 be a little confusing it comes up by 00:15:54.26000:15:54.270 default in the parallel mode and it 00:16:00.76900:16:00.779 actually checked I think you check 00:16:03.68000:16:03.690 capacitance better as we get into it I 00:16:05.93000:16:05.940 think it check capacitance better 00:16:07.46000:16:07.470 typically in parallel mode but in series 00:16:11.60000:16:11.610 mode it's seen the show a true ESR so 00:16:16.87000:16:16.880 we'll look at that a little more as we 00:16:18.92000:16:18.930 get into it but this one also does not 00:16:21.62000:16:21.630 have a discharge auto discharge it tells 00:16:25.55000:16:25.560 you to discharge the capacitor before 00:16:27.92000:16:27.930 testing so we'll look at now we'll go 00:16:32.78000:16:32.790 through a few tests with these and 00:16:34.10000:16:34.110 compare them there's a safety precaution 00:16:38.93000:16:38.940 we're gonna be dealing with some very 00:16:41.15000:16:41.160 large and very powerful capacitors this 00:16:44.87000:16:44.880 one in particular is 20 2 micro farad at 00:16:49.00000:16:49.010 450 volts rate it's a lot of charge it's 00:16:54.17000:16:54.180 a pretty heavy capacitor and even this 00:16:56.56900:16:56.579 one it may look small to comparison but 00:16:58.76000:16:58.770 it's a 560 micro farad at 200 volts so 00:17:03.13900:17:03.149 it's also a high rated capacitor so what 00:17:07.22000:17:07.230 I'm gonna do is charge it up with a 00:17:12.06900:17:12.079 instead of my power supply I have this 00:17:15.07900:17:15.089 56 volt battery is fully charged that 00:17:18.11000:17:18.120 are charged it up very quickly I have a 00:17:23.65000:17:23.660 470 ohm resistor with some leads and 00:17:27.54900:17:27.559 these leaves have a little resistance to 00:17:30.04900:17:30.059 they're not the best quality 00:17:32.38000:17:32.390 actually works out pretty good for 00:17:35.11000:17:35.120 discharging capacitors if you want to 00:17:39.74000:17:39.750 charge this up always when charging the 00:17:42.08000:17:42.090 capacitor you want to keep your polarity 00:17:44.42000:17:44.430 correct if you don't it can blow up in 00:17:46.19000:17:46.200 your hand your face it's a quick charge 00:17:51.92000:17:51.930 there straight on straight across this 00:18:01.42000:18:01.430 capacitor close to a lethal level now we 00:18:08.51000:18:08.520 cut it on immediately it says 52 volts 00:18:11.75000:18:11.760 please discharge or capacitor now it 00:18:16.16000:18:16.170 went down enough that it's actually 00:18:17.54000:18:17.550 discharged and automatically discharged 00:18:21.77000:18:21.780 that intensity just that quick this 00:18:23.45000:18:23.460 meter is really good at doing that but 00:18:29.27000:18:29.280 always be very very careful and make 00:18:32.99000:18:33.000 sure you capacitors you know the method 00:18:36.56000:18:36.570 of taking and running a screwdriver 00:18:37.88000:18:37.890 across it it works well to make sure 00:18:40.76000:18:40.770 that it doesn't have enough charge to 00:18:43.76000:18:43.770 hurt you 00:18:44.57000:18:44.580 he he trailed it to art then hurt you 00:18:47.08000:18:47.090 but also I'm gonna charge this one up 00:18:51.71000:18:51.720 and it's gonna art too now even even 00:18:59.69000:18:59.700 charging this thing up at that level 00:19:05.74000:19:05.750 which is a 450 vote now but it is saying 00:19:11.72000:19:11.730 is 55 volts 00:19:12.98000:19:12.990 safely discharges so it's letting you 00:19:14.84000:19:14.850 know it warns you unless you know that 00:19:19.19000:19:19.200 it can't discharge it at that level 00:19:20.81000:19:20.820 safely so at this point we can take our 00:19:24.19000:19:24.200 resistor and leads and we can discharge 00:19:28.40000:19:28.410 it 00:19:32.65900:19:32.669 you can see them leader there 00:19:37.62000:19:37.630 and it is discharged this time I have 00:19:47.04900:19:47.059 this large capacitor charged up again I 00:19:49.18000:19:49.190 want you to be able to see the voltage 00:19:51.76000:19:51.770 on the screen and by taking the resistor 00:19:56.74000:19:56.750 and a jumper and going across I want you 00:20:03.10000:20:03.110 to be able to see how slowly it 00:20:07.81000:20:07.820 discharges it's rapid enough to 00:20:10.53900:20:10.549 discharge quickly but yet it doesn't do 00:20:16.03000:20:16.040 it in a high rate in the arc because 00:20:22.51000:20:22.520 honestly with this with this capacitor 00:20:24.94000:20:24.950 there 450 volts charged I would not want 00:20:28.18000:20:28.190 to discharge it straight across for the 00:20:32.23000:20:32.240 bus so would demonstrate that with just 00:20:35.89000:20:35.900 56 bolts on it it's pretty uh it's 00:20:39.19000:20:39.200 pretty big bang so once again we got 00:20:46.09000:20:46.100 this large capacitor charged up this is 00:20:49.93000:20:49.940 right at 55 volts on it 00:20:52.23000:20:52.240 55 volts at 2200 microfarad is is fairly 00:20:58.48000:20:58.490 large but it's nothing compared to the 00:21:00.73000:21:00.740 450 volts so it's a pretty big pop so 00:21:09.21000:21:09.220 enough to scare you so that way by using 00:21:16.21000:21:16.220 a resistor it can be a little less 00:21:19.12000:21:19.130 intense but nonetheless at least 00:21:22.53900:21:22.549 Alicia's use a screwdriver or a jumper 00:21:24.70000:21:24.710 to make sure they are totally discharged 00:21:27.60000:21:27.610 before moving forward because some of 00:21:30.07000:21:30.080 these can be at lethal voltages most 00:21:33.52000:21:33.530 circuits in there either in circuit most 00:21:36.34000:21:36.350 of them do have a bleed resistor which 00:21:39.54900:21:39.559 you can't always rely on that they can 00:21:41.59000:21:41.600 be faulty as well and you can't you 00:21:43.99000:21:44.000 can't always rely that they actually 00:21:45.34000:21:45.350 have one in circuit either so always 00:21:49.71000:21:49.720 rather safe than sorry now not only for 00:21:53.71000:21:53.720 your sake but also the meters because 00:21:55.39000:21:55.400 not all of them have a safe to do it in 00:21:57.19000:21:57.200 if the peak does so I always keep that 00:22:00.13000:22:00.140 in mind once again I have these 00:22:06.27000:22:06.280 capacitors charged up to about 55 56 00:22:09.31000:22:09.320 votes discharges straight across the 00:22:11.89000:22:11.900 terminals this 560 micro farad at 200 00:22:20.83000:22:20.840 volt also charged up to about 56 volts 00:22:28.47000:22:28.480 so that's the difference I'm putting a 00:22:33.19000:22:33.200 resistor across or just below 50 folks 00:22:36.90900:22:36.919 just letting that discharge it so again 00:22:41.11000:22:41.120 this was charged up to a truth 450 00:22:44.95000:22:44.960 voltage all that it would uh it would 00:22:47.02000:22:47.030 take a chunk out of the screwdriver 00:22:48.34000:22:48.350 shank so just always be aware of what 00:22:52.18000:22:52.190 you have in comparison to their eye both 00:22:57.99000:22:58.000 or all or electrolytic but if there's a 00:23:01.03000:23:01.040 big difference between this little small 00:23:04.81000:23:04.820 one and and of course the larger variety 00:23:16.37000:23:16.380 okay so one thing to remember about 00:23:19.60000:23:19.610 capacitor we're actually two things to 00:23:23.33000:23:23.340 remember about capacitor and ESR 00:23:27.17000:23:27.180 check-in is the first thing safety we 00:23:30.47000:23:30.480 covered that cover yourself 00:23:32.60000:23:32.610 make sure you capacitor discharge they 00:23:34.43000:23:34.440 can harm you especially the larger 00:23:37.10000:23:37.110 variety they can go up to 450 volts of 00:23:39.29000:23:39.300 high-capacity but anything over over 50 00:23:43.37000:23:43.380 volts can be deadly so be careful the 00:23:48.08000:23:48.090 next thing to really consider when you 00:23:50.03000:23:50.040 do an ESR testing is think about the the 00:23:54.50000:23:54.510 low resistance of the test what your 00:23:57.80000:23:57.810 chicken is ultra low or very low ohms so 00:24:03.08000:24:03.090 the resistance does matter so if we use 00:24:05.69000:24:05.700 this GM 328 we can very easily put some 00:24:10.31000:24:10.320 clips in here and the lows if socket and 00:24:14.69000:24:14.700 close it up so it makes it real handy 00:24:18.95000:24:18.960 right well for some things the reason 00:24:23.75000:24:23.760 that zip suck it's so important is it's 00:24:25.82000:24:25.830 very low ohms to the trace so it's 00:24:29.84000:24:29.850 designed to be as close as you can 00:24:32.30000:24:32.310 especially ESR low ohms reading if we 00:24:35.54000:24:35.550 were to short this out and do a test 00:24:37.19000:24:37.200 right now it's a bit one of the best 00:24:40.37000:24:40.380 ways to do this one two three is showing 00:24:45.35000:24:45.360 a resistance of one point three three 00:24:46.88000:24:46.890 ohms and I did that just to show that 00:24:50.87000:24:50.880 how crappy some leaves can be it's the 00:24:53.00000:24:53.010 bees look cheap like eBay the leaves are 00:24:57.02000:24:57.030 just are just that much resistance and 00:24:59.00000:24:59.010 it's a really crappy connection we can 00:25:02.21000:25:02.220 we can remedy some of that but just to 00:25:04.67000:25:04.680 show the little crimp don't forward it 00:25:07.40000:25:07.410 back they're not even soldered so just 00:25:10.01000:25:10.020 be careful what you do with leads this 00:25:13.22000:25:13.230 is probably an exaggerated case because 00:25:15.05000:25:15.060 the lead to such poor quality but it 00:25:17.57000:25:17.580 just goes to show that it doesn't matter 00:25:20.47000:25:20.480 because what we're checking for is down 00:25:24.95000:25:24.960 some of these capacitors the larger they 00:25:27.89000:25:27.900 get like point zero 00:25:29.72000:25:29.730 so you can see we already out of spec 00:25:33.22000:25:33.230 for a neck for an example I'll just use 00:25:36.65000:25:36.660 this one for an example let's say 2200 00:25:40.61000:25:40.620 microfarad at 16 volts put it on here 00:25:45.38000:25:45.390 with these leaves let's see what IES are 00:25:49.34000:25:49.350 at the test tells us checking the 00:25:54.20000:25:54.210 capacitance capacitance checks good 00:25:56.72000:25:56.730 which you know through the resistance 00:26:01.10000:26:01.110 and the wire the capacitance show up 00:26:02.66000:26:02.670 okay typically just a little bit lower 00:26:04.49000:26:04.500 but 0.75 on that's that's pretty bad if 00:26:11.24000:26:11.250 we look at the chart here at 16 volts we 00:26:14.12000:26:14.130 should be at point zero seven so well 00:26:18.35000:26:18.360 that's a bad cap well let's do the same 00:26:21.62000:26:21.630 test this time putting it across the ZIF 00:26:27.83000:26:27.840 socket directly 00:26:36.81000:26:36.820 and point 1 1 so it's really close so 00:26:42.30000:26:42.310 according to this we're still a little 00:26:46.71000:26:46.720 bit higher sorry we're still a little 00:26:48.72000:26:48.730 bit higher than it should be but I think 00:26:53.16000:26:53.170 that capacitor is ok it's not showing a 00:26:55.59000:26:55.600 tremendous variance from from the 00:26:58.80000:26:58.810 typical chart and at that point if it 00:27:01.68000:27:01.690 really matters to you I would look up 00:27:03.36000:27:03.370 actual manufacturer and see you 200 00:27:05.37000:27:05.380 kilohertz what it actually the 00:27:07.68000:27:07.690 manufacturer states the specs for that 00:27:09.54000:27:09.550 capacitor should be so with that being 00:27:13.08000:27:13.090 said this look capacitor does a little 00:27:15.93000:27:15.940 Kester does do a good job with 00:27:17.34000:27:17.350 capacitance an ESR just always keep in 00:27:19.89000:27:19.900 mind it matters about leads which it's 00:27:24.72000:27:24.730 also one reason all these meters come 00:27:26.76000:27:26.770 with little short leads even even this 00:27:30.99000:27:31.000 high-dollar meter has got some pretty 00:27:32.94000:27:32.950 short leads and these are a little 00:27:37.23000:27:37.240 longer but they are high quality really 00:27:39.72000:27:39.730 high quality leads and they do work well 00:27:43.58000:27:43.590 but we always have to zero WiDi meter 00:27:46.74000:27:46.750 and we have to make sure that the leads 00:27:49.32000:27:49.330 are short it's possible doing the 100 00:27:53.22000:27:53.230 kilohertz check the ESR okay now we're 00:27:59.16000:27:59.170 back with the GM 328 I got a few 00:28:02.22000:28:02.230 capacitors here to check I had a bunch 00:28:04.20000:28:04.210 more up there and even some more back in 00:28:06.24000:28:06.250 the back of the beach to check I 00:28:09.33000:28:09.340 realized it was going to take a lot of 00:28:11.07000:28:11.080 time didn't want to bore you to death to 00:28:12.72000:28:12.730 the video try to keep it as short as we 00:28:15.63000:28:15.640 can so I just got I got four capacitors 00:28:19.29000:28:19.300 up here one of them I know as a failed 00:28:21.18000:28:21.190 capacitor I didn't actually keep many 00:28:24.36000:28:24.370 from repair jobs but I did actually have 00:28:27.48000:28:27.490 this one you can see the very typical 00:28:30.86000:28:30.870 boat and the swell factor of this 00:28:35.87000:28:35.880 capacitor it was a good a good name 00:28:39.24000:28:39.250 brand and a good style capacitors just 00:28:45.24000:28:45.250 over time his actions over 20 years old 00:28:47.16000:28:47.170 so just 00:28:49.52900:28:49.539 time for they don't they don't have a 00:28:51.23900:28:51.249 very long life electrolytic so we'll 00:28:54.50900:28:54.519 check will check these forward one known 00:28:56.82000:28:56.830 bad one and then I also wanted to take 00:29:00.33000:29:00.340 time to get into some well do some in 00:29:02.46000:29:02.470 circuit just on a board that I have got 00:29:06.38900:29:06.399 a large cap here we got some I probably 00:29:08.51900:29:08.529 check this one here on board 00:29:13.46000:29:13.470 got a little Stepford driver here 00:29:15.69000:29:15.700 probably check this big cap here it's 00:29:18.41900:29:18.429 one of the during my move it got dented 00:29:21.18000:29:21.190 up we'll check it and see hey is it 00:29:22.83000:29:22.840 still okay check okay or special if it 00:29:27.69000:29:27.700 doesn't show short or anything like that 00:29:29.31000:29:29.320 so so we'll get into testing with this 00:29:32.09900:29:32.109 GM 328 first I got the large 2200 00:29:36.14900:29:36.159 microfarad 450 vote capacitor I'm gonna 00:29:39.26900:29:39.279 cut this bench light up I believe it'll 00:29:41.03900:29:41.049 be better they glare on the screen but 00:29:46.46900:29:46.479 first of all let me uh any zero after 00:29:49.04900:29:49.059 leaves here or at least show you what it 00:29:52.25900:29:52.269 is we can't go through round we can go 00:29:57.93000:29:57.940 through a person we can't go through a 00:29:59.43000:29:59.440 procedure and actually point zero seven 00:30:02.72900:30:02.739 so you can go through and self-test and 00:30:05.36900:30:05.379 zero out the leads wherever they are let 00:30:08.12900:30:08.139 it go through a calibration check but we 00:30:11.60900:30:11.619 know we point zero seven a point zero 00:30:15.65900:30:15.669 eight what I read earlier I wrote that 00:30:17.31000:30:17.320 down and we getting point one five 00:30:22.93000:30:22.940 went one 5 2012 micro fire 00:30:27.22000:30:27.230 okay wrote that down let's go onto the 00:30:29.96000:30:29.970 next one this is the 560 microfiber 200 00:30:40.85000:30:40.860 volt and it's showing point four eight 00:31:02.79000:31:02.800 point one five that's what I got earlier 00:31:06.87000:31:06.880 I think I had a bad connection on them 00:31:08.70000:31:08.710 it doesn't matter they got a really 00:31:11.43000:31:11.440 least need to be on there good and tight 00:31:14.30000:31:14.310 you talking about 00:31:16.11000:31:16.120 less than an own bag it don't take much 00:31:17.88000:31:17.890 to change the reading yeah point one 00:31:22.08000:31:22.090 four that's more like what I was getting 00:31:24.21000:31:24.220 earlier when I checked it alright now 00:31:27.96000:31:27.970 this is the one that's known defective 00:31:29.88000:31:29.890 one of the test here is with all the 00:31:32.10000:31:32.110 meters pick up the good ones being close 00:31:34.68000:31:34.690 to in tolerance and will they pick up 00:31:36.33000:31:36.340 the bad one being defective and we show 00:31:43.98000:31:43.990 on a 1274 nanofarad and and look at that 00:31:48.72000:31:48.730 as point 0.14 K ohm 9.14 so poaches loss 00:31:56.94000:31:56.950 of 23% so we're showing there's 250 volt 00:32:02.10000:32:02.110 20 2 micro farad and showing almost any 00:32:06.48000:32:06.490 capacitance where it should be and then 00:32:09.15000:32:09.160 the resistance is showing way high so 00:32:11.88000:32:11.890 some of these meters won't even read 00:32:13.89000:32:13.900 that high so it picked up the effective 00:32:17.04000:32:17.050 one definitely picked it up as defective 00:32:19.64000:32:19.650 we have a 68 hundred microfarad at 35 00:32:23.46000:32:23.470 volts 00:32:41.19000:32:41.200 point one o 8313 this one actually reads 00:32:47.61000:32:47.620 hi by all the meters next we'll try do 00:32:55.40900:32:55.419 an insert it check 00:33:06.24000:33:06.250 these leads do have some loss but it's 00:33:08.76000:33:08.770 not it's not real bad that's point zero 00:33:12.42000:33:12.430 seven relative alright so we have a 25 00:33:21.30000:33:21.310 14 at point one one well off so check 00:33:33.69000:33:33.700 this one up here see that large the one 00:33:35.88000:33:35.890 easy to get to on the edge of the board 00:33:37.47000:33:37.480 I think you can see that okay hopefully 00:33:41.79000:33:41.800 it'll make a good connection 00:33:52.39000:33:52.400 we could also you can also go into this 00:33:55.43000:33:55.440 meter and we can hold it down and go in 00:33:59.24000:33:59.250 and set up new keep hitting the button 00:34:06.35000:34:06.360 until we come down to ESR capacitor plus 00:34:10.01000:34:10.020 yes yes all right so one in three though 00:34:12.71000:34:12.720 I may have to change my hold it down I 00:34:16.18000:34:16.190 think I'll have to change mine I got it 00:34:20.89900:34:20.909 on one and two 00:34:36.52000:34:36.530 so if you can see that when it's on this 00:34:40.62900:34:40.639 mode you can actually just clip it to 00:34:43.21000:34:43.220 something it actually itself like out of 00:34:48.22000:34:48.230 the tech did you will except detect 00:34:51.45000:34:51.460 start showing the capacitance and this 00:34:54.70000:34:54.710 series resistance on the screen so that 00:34:57.82000:34:57.830 way you can do it hands-free hope you 00:35:01.12000:35:01.130 can see this on camera sorry 00:35:06.64000:35:06.650 there we go we've got 48 micro farad and 00:35:10.71000:35:10.720 point 0.99 2.0 point 9 8 ohms and this 00:35:21.97000:35:21.980 is a 47 micro farad can you see that 00:35:24.60900:35:24.619 okay no it's a 47 micro farad as 63 00:35:33.54900:35:33.559 votes 00:35:36.42000:35:36.430 it's the 85 c rated capacitor so it's 00:35:40.53900:35:40.549 not the highest quality or high seen 00:35:43.24000:35:43.250 capacitor for example this one I didn't 00:35:46.35900:35:46.369 mention that but this one is 105 see 00:35:48.87000:35:48.880 it's right on the top there 105 C 00:35:52.74000:35:52.750 typically you higher switching capacity 00:35:57.27900:35:57.289 and like lower ESR capacitors are rated 00:36:01.28900:36:01.299 for that higher temperature we got one 00:36:04.18000:36:04.190 more here to check in circuit 00:36:15.26000:36:15.270 eighty two hundred microfarad at fifty 00:36:18.45000:36:18.460 working votes and is showing 8.15 00:36:25.59000:36:25.600 military or 8150 microfarad at point 00:36:31.80000:36:31.810 zero eight or point one on I typically 00:36:41.16000:36:41.170 used as if socket on nine percent of the 00:36:43.29000:36:43.300 test if I can on this on this meter so 00:36:46.26000:36:46.270 something some of this a plug right in 00:36:49.52000:36:49.530 but I mention in the previous video 00:36:51.72000:36:51.730 about this that you can you can solder 00:36:53.85000:36:53.860 your own leads only get a better 00:36:55.11000:36:55.120 connection or and even even going 00:36:58.95000:36:58.960 through the calibration whether we're 00:37:00.87000:37:00.880 the lead on there and actually getting 00:37:03.18000:37:03.190 it closer to zero if it's way off on you 00:37:05.46000:37:05.470 point zero seven wasn't a big deal for 00:37:07.56000:37:07.570 me this time I just wrote it down and 00:37:09.90000:37:09.910 I'll subtract that accordingly but 00:37:11.51000:37:11.520 either way you can do it either way it 00:37:13.92000:37:13.930 actually work quite well going up in 00:37:18.45000:37:18.460 there just the order of expense will go 00:37:20.76000:37:20.770 to this little end me up mes are one 00:37:24.60000:37:24.610 hundred just a straight ESR meter so 00:37:30.48000:37:30.490 we'll cut this on make sure the displace 00:37:32.82000:37:32.830 shows up okay on camera I believe it's 00:37:36.87000:37:36.880 better down and up I think the glare is 00:37:40.62000:37:40.630 worse the way my lighting is we'll bring 00:37:44.85000:37:44.860 in the big twenty two hundred check it 00:37:52.84900:37:52.859 and it auto ranges to the 0 to 1 ohm 00:37:55.96900:37:55.979 range and shows point zero one owns and 00:38:01.00900:38:01.019 it tells you just good for a cat with 00:38:03.44000:38:03.450 Louis yes our but it's referencing a 00:38:06.58900:38:06.599 twenty five boat let your let it cap so 00:38:10.16000:38:10.170 that's the only thing is you got to 00:38:12.14000:38:12.150 watch what it's referencing just because 00:38:13.81900:38:13.829 it says good it may not always be good 00:38:18.94000:38:18.950 one thing I failed to do was the I meant 00:38:22.99900:38:23.009 to show you the zero first which is 00:38:26.77900:38:26.789 still dead I open earlier when I did it 00:38:28.54900:38:28.559 on the video we'll go through and check 00:38:32.98900:38:32.999 the 5560 microfarad it's showing good 00:38:40.99900:38:41.009 point zero two seven will go to the one 00:38:50.02900:38:50.039 that's the null failed capacitor and it 00:38:58.91000:38:58.920 shows you know from that from the 10 to 00:39:01.43000:39:01.440 100 ranges over range overload it's 00:39:05.63000:39:05.640 actually um showing that it it can't 00:39:08.26900:39:08.279 even read it it said it was a reading 00:39:11.66000:39:11.670 his overflow so letting you know 00:39:13.75900:39:13.769 something is definitely going on there 00:39:15.19900:39:15.209 didn't pick up a circuit at all 00:39:25.19000:39:25.200 point zero 100 point zero one six 00:39:29.69000:39:29.700 showing that it's good I didn't have a 00:39:33.06000:39:33.070 good connection on that one actually 00:39:34.35000:39:34.360 your next song on the camera moving 00:39:36.39000:39:36.400 before I did good in circuit will bring 00:39:51.18000:39:51.190 this board back in with a 2700 shorted 00:39:58.53000:39:58.540 leaves can be a little challenging but 00:40:00.74000:40:00.750 like I say in the long run especially 00:40:02.94000:40:02.950 the hundred kilohertz you want to be as 00:40:05.76000:40:05.770 short as possible it's showing good 00:40:12.86000:40:12.870 we'll go ahead and check this little one 00:40:15.24000:40:15.250 like we did with the 328 small when 00:40:23.22000:40:23.230 you're gonna show a higher resistance 00:40:29.75000:40:29.760 Oh point five for one 00:40:37.73000:40:37.740 and then we also did this on the 328 00:40:54.22000:40:54.230 and the showing point zero one 00:41:04.72000:41:04.730 you know overall this meters quick and 00:41:07.00000:41:07.010 handy it does a good job and the one 00:41:09.28000:41:09.290 thing you may have already noticed just 00:41:10.87000:41:10.880 a problem to me with this meter I knew 00:41:13.45000:41:13.460 it when I bought it that it was simply a 00:41:15.10000:41:15.110 TSR meter but for the money it wasn't a 00:41:18.04000:41:18.050 bad a bad deal it's not a bad little 00:41:20.17000:41:20.180 meter but you can buy the capacitance 00:41:23.38000:41:23.390 meter all the ESR meter I do prefer to 00:41:25.99000:41:26.000 have them both in one because it really 00:41:27.79000:41:27.800 does matter you looking for most of dead 00:41:29.71000:41:29.720 short but if you kept if you capacitor 00:41:31.75000:41:31.760 is shorted it can almost show goods and 00:41:34.60000:41:34.610 you got to really watch that I really 00:41:37.27000:41:37.280 learned over the years I really like I 00:41:39.21000:41:39.220 like one they were fixing to come to 00:41:42.01000:41:42.020 next that shows the capacitance and the 00:41:45.72000:41:45.730 ESR together all the rest of them here 00:41:49.27000:41:49.280 today do they do just that so we get 00:41:53.62000:41:53.630 into one of my favorites here the little 00:41:57.28000:41:57.290 peak go ahead and hook it up one thing 00:42:03.31000:42:03.320 about this peak is this it's really it's 00:42:05.92000:42:05.930 also hands off once you cut this on get 00:42:08.77000:42:08.780 a show analyzing either read the 00:42:12.31000:42:12.320 capacitor it usually give you a SR 00:42:14.89000:42:14.900 before it even has time to fully rise on 00:42:18.58000:42:18.590 a large capacitor depending on the value 00:42:20.50000:42:20.510 it's going to take a little longer but I 00:42:22.29000:42:22.300 mean right off the bat is quick nineteen 00:42:25.06000:42:25.070 fifty eight point zero two actually 00:42:29.32000:42:29.330 shows the capacitance spec 00:42:42.50000:42:42.510 point zero 6 ohms see if it'll pick up 00:42:50.06900:42:50.079 the bad one a open circuit or low 00:42:56.46000:42:56.470 capacitance think it's both 00:43:21.89000:43:21.900 took a while this is the high value 00:43:24.11000:43:24.120 capacitor point zero five on for me it's 00:43:28.85000:43:28.860 a big help to show the capacitance value 00:43:30.59000:43:30.600 on screen without having to go back and 00:43:34.76000:43:34.770 check them when you have a low low ohms 00:43:37.04000:43:37.050 reading here we go to 2700 00:43:48.61000:43:48.620 point zero one 24:46 I can do the little 00:43:58.72000:43:58.730 one on this one too I forgot and these 00:44:02.44000:44:02.450 these low alligator clips do grab good 00:44:04.63000:44:04.640 on these leads even on on the board I 00:44:07.72000:44:07.730 can let them go in point six six fifty 00:44:11.86000:44:11.870 one like a very good deal last but not 00:44:17.26000:44:17.270 least since we are doing a comparison 00:44:23.16000:44:23.170 try to do them all it's already ten ones 00:44:28.63000:44:28.640 point zero two on the es are seventy 00:44:34.51000:44:34.520 nine sixty two and being an in circuit 00:44:39.76000:44:39.770 test where did it quick all right well 00:44:47.83000:44:47.840 this by far one of my favorites so far 00:44:53.13000:44:53.140 but next we bring in the high dollar job 00:44:55.90000:44:55.910 and surely it's better 00:44:58.51000:44:58.520 well maybe I'm gonna try to make this as 00:45:04.69000:45:04.700 quick and painless as possible because 00:45:07.36000:45:07.370 it's this meter here has a lot to it so 00:45:11.02000:45:11.030 I want you to see the features of it and 00:45:13.90000:45:13.910 compare it with the ESR reading of the 00:45:17.14000:45:17.150 other meters we had the day but I guess 00:45:19.78000:45:19.790 it's it's so feature-rich that it can be 00:45:24.67000:45:24.680 a little bit time-consuming to explain a 00:45:26.95000:45:26.960 lot of the functions of it but one thing 00:45:29.32000:45:29.330 we are talked about is the different 00:45:30.85000:45:30.860 frequencies the paralleled a series 00:45:32.89000:45:32.900 checking so just to mention that the 00:45:38.74000:45:38.750 book tells you it defaults to parallel 00:45:42.07000:45:42.080 on the reading photo for the ESR and it 00:45:48.28000:45:48.290 says in capacitance both it reads both 00:45:50.80000:45:50.810 you can have a submenu so you got you 00:45:53.14000:45:53.150 got the main and then the secondary 00:45:55.56000:45:55.570 display so we have capacitance and then 00:45:58.69000:45:58.700 we'll have the ESR up top and 00:46:01.04000:46:01.050 smaller font but it defaults to parallel 00:46:07.40000:46:07.410 and you'll see PA are on the screen and 00:46:09.83000:46:09.840 then if you hold it down and go to serie 00:46:12.08000:46:12.090 series they recommend series for more of 00:46:15.59000:46:15.600 inductance and they recommend the 00:46:18.65000:46:18.660 parallel for capacitance and resistance 00:46:20.27000:46:20.280 so just checking out a circuit you would 00:46:23.30000:46:23.310 think you would definitely use a 00:46:24.35000:46:24.360 parallel but you kind of gotta play 00:46:27.11000:46:27.120 around with it and see what works the 00:46:28.55000:46:28.560 best and also they recommend anything 00:46:32.81000:46:32.820 that's less than point zero 1 microfarad 00:46:35.39000:46:35.400 which we don't have anything like that 00:46:36.92000:46:36.930 today they like use 1 kilohertz signal 00:46:41.99000:46:42.000 to check it but they're actually saying 00:46:44.99000:46:45.000 anything greater than 10 microfarad to 00:46:47.84000:46:47.850 use 120 Hertz which is a little bit odd 00:46:51.77000:46:51.780 as we mentioned earlier but all the rest 00:46:55.85000:46:55.860 of these meters well it with the 00:47:00.17000:47:00.180 exception of this one uses 100 kilohertz 00:47:02.71000:47:02.720 so and that that's typical of it yes our 00:47:08.24000:47:08.250 meter is they use 100 kilohertz because 00:47:10.55000:47:10.560 I think that's what the factory of most 00:47:13.25000:47:13.260 capacitor is right there and based their 00:47:15.77000:47:15.780 ratings and specs of capacitors on so 00:47:20.66000:47:20.670 we're getting into this one will cut it 00:47:23.18000:47:23.190 on do it a capacitance what's already on 00:47:29.38000:47:29.390 capacitance and we'll go to ESR 00:47:37.53000:47:37.540 we're short out the leads and do a check 00:47:44.90000:47:44.910 actually let me see what frequency this 00:47:47.28000:47:47.290 is on one kilohertz but let's go to the 00:47:51.66000:47:51.670 100 or 120 kilohertz me 1 120 Hertz I'm 00:47:55.53000:47:55.540 sorry 00:47:56.57000:47:56.580 and then let's let's go to let's leave 00:47:59.82000:47:59.830 it on parallel that's what they kind of 00:48:01.47000:48:01.480 recommend for checking in our range and 00:48:04.88000:48:04.890 we will take these little leads and 00:48:37.32900:48:37.339 okay 00:48:40.35900:48:40.369 there we go 00:48:46.12000:48:46.130 turn this to the right polarity 00:48:59.44000:48:59.450 and he's showing 1.88 military to 1880 00:49:05.57900:49:05.589 microfarad so but the ESR is point zero 00:49:11.17000:49:11.180 three nine or so actually showing like 00:49:14.07900:49:14.089 this capacitor maybe just a little bit 00:49:16.69000:49:16.700 out of Tolerance on the on the ESR but 00:49:20.23000:49:20.240 now that the peak actually showed it to 00:49:22.12000:49:22.130 be within tolerance 00:49:31.76000:49:31.770 without looking does that expects up of 00:49:34.19000:49:34.200 that when it's really close to the 00:49:35.42000:49:35.430 tolerance 00:49:46.75900:49:46.769 5:06 and point zero eight six showing 00:49:55.47000:49:55.480 just a little bit out also what I'm 00:49:58.62000:49:58.630 going to show now before I go much 00:50:00.18000:50:00.190 further I'm going to show the difference 00:50:01.65000:50:01.660 in the series hold it down and go to the 00:50:04.10900:50:04.119 series 00:50:12.44000:50:12.450 you 00:50:42.39000:50:42.400 0-3 00:50:49.47000:50:49.480 I know some of them I shared a good bit 00:50:52.23000:50:52.240 different being his series than it did 00:50:55.41000:50:55.420 parallel once he wrote a let's check the 00:51:06.93000:51:06.940 backup a sitter with it 00:51:15.74000:51:15.750 sheron's attend an affair it's an 00:51:19.35000:51:19.360 absolutely no reading of ohms on its 00:51:22.17000:51:22.180 scale so definitely picked up the back 00:51:25.11000:51:25.120 of Pastor that's every one of them we 00:51:26.97000:51:26.980 try the day did pick up the bad one I 00:51:28.95000:51:28.960 wish I had more bad ones still around I 00:51:31.56000:51:31.570 usually toss them I don't really think 00:51:33.00000:51:33.010 about saving them point zero to six or 00:51:42.21000:51:42.220 seven point three million let's try some 00:51:51.00000:51:51.010 in circuit 00:51:51.87000:51:51.880 here's that 2700 think it doesn't matter 00:51:56.49000:51:56.500 about polarity 00:52:11.66000:52:11.670 two point three four five million point 00:52:15.55900:52:15.569 zero one eight five ohms shows good 00:52:26.56000:52:26.570 I grabbed pretty good my quiet you know 00:52:34.96000:52:34.970 say there it goes 00:52:41.64000:52:41.650 almost 46 45.6 microfarad what 1.65 00:52:46.92000:52:46.930 that's good and last but not least 00:53:12.89000:53:12.900 he's showing 7.39 Milly 0.036 that was 00:53:19.40000:53:19.410 good 00:53:26.80000:53:26.810 so summing things up every meter here 00:53:30.58000:53:30.590 from the least expensive less than $20 00:53:33.33000:53:33.340 category up to the 250 to $300 category 00:53:39.66000:53:39.670 every meter here ESR wise actually 00:53:43.96000:53:43.970 checked in circuit and out of circuit 00:53:46.30000:53:46.310 capacitors relatively across the board 00:53:50.35000:53:50.360 the same as far as a pass and failed 00:53:52.33000:53:52.340 American measure this one only checks 00:53:57.10000:53:57.110 ESR but still they found the only known 00:54:00.58000:54:00.590 bad one they showed us the ones that 00:54:03.82000:54:03.830 were on the fence kind of borderline but 00:54:05.83000:54:05.840 they all the hour showed that it was 00:54:07.27000:54:07.280 about borderline which on the higher 00:54:11.86000:54:11.870 range of things that does get very low 00:54:14.61000:54:14.620 so this is price-wise if I were to maybe 00:54:23.98000:54:23.990 rearrange these to being the most the 00:54:26.53000:54:26.540 most useful maybe the most useful the 00:54:30.46000:54:30.470 easiest the ease of use and the most 00:54:33.43000:54:33.440 reliability and quick of testing will 00:54:37.63000:54:37.640 probably probably still being this this 00:54:41.95000:54:41.960 order I mean both of these are made 00:54:45.76000:54:45.770 where and this one as well just checking 00:54:49.87000:54:49.880 yeah ESR wise this one is just as easy 00:54:52.36000:54:52.370 as any of them but checking these are 00:54:54.85000:54:54.860 checking but just the fact that it's on 00:54:57.37000:54:57.380 the ESR meter don't show capacitance as 00:54:59.98000:54:59.990 well while you're testing for that 00:55:02.11000:55:02.120 region that's always gonna rank a little 00:55:03.73000:55:03.740 low this one has such a high-end use for 00:55:08.59000:55:08.600 other things but just for strictly boy 00:55:11.83000:55:11.840 checking electrolytic caps switch mode 00:55:15.04000:55:15.050 power supplies and things of that nature 00:55:16.51000:55:16.520 where you're just looking for the ESR I 00:55:19.08000:55:19.090 really don't go to this one that often 00:55:21.16000:55:21.170 it's a little bit tedious you have to 00:55:24.01000:55:24.020 play with the frequency and where this 00:55:25.65000:55:25.660 parallel and series and these here just 00:55:28.03000:55:28.040 work so this is really my go-to I really 00:55:32.20000:55:32.210 like the look peak it works well the 00:55:34.66000:55:34.670 leads are nice the clips are good on it 00:55:37.80000:55:37.81000:55:39.38000:55:39.390 I just talked about the good things 00:55:42.14000:55:42.150 about it for a second the auto discharge 00:55:44.35900:55:44.369 is really neat about it because in 00:55:46.51900:55:46.529 circuit where there has a bleed resistor 00:55:48.50000:55:48.510 or not it does a good job don't the only 00:55:51.89000:55:51.900 negative thing about this one is it does 00:55:53.75000:55:53.760 take the little twelve volt the 23 a 00:55:57.01900:55:57.029 series a little bit a little bit harder 00:56:00.07900:56:00.089 they get into with the three screws but 00:56:01.64000:56:01.650 not a big deal not quite as easy as the 00:56:04.16000:56:04.170 rest of these to replace which you know 00:56:07.00900:56:07.019 they all have some type of battery door 00:56:09.55900:56:09.569 when I swing a screw but with that said 00:56:15.65000:56:15.660 this being the 60 to 70 being a better 00:56:18.28900:56:18.299 version with more features the the specs 00:56:22.54900:56:22.559 on the CSR 70 actually state that it's a 00:56:26.56900:56:26.579 triple-a battery if that's correct then 00:56:28.22000:56:28.230 the triple-a battery would be a lot a 00:56:30.41000:56:30.420 lot easier to come by I do keep some 12 00:56:33.50000:56:33.510 volts around for the source no big deal 00:56:34.97000:56:34.980 to me that's about the only negative 00:56:37.37000:56:37.380 thing I got for the for the whole thing 00:56:39.68000:56:39.690 and it's naive an issue with the 70 00:56:41.24000:56:41.250 series the SR 70 mile this one again 00:56:46.19000:56:46.200 just rank really high good little meter 00:56:48.76900:56:48.779 for the money great to have around well 00:56:50.69000:56:50.700 worth it this one for the money 00:56:53.15000:56:53.160 I think it's fifty five bucks not not 00:56:54.82900:56:54.839 bad just about if I had my choice I 00:56:58.06900:56:58.079 would always have like it's like a 00:56:59.32900:56:59.339 passing it showing this one pretty much 00:57:01.91000:57:01.920 do it all yes kind of a painting a 00:57:05.12000:57:05.130 thesis to set up and get ready but it 00:57:07.97000:57:07.980 does have a lot of features I didn't 00:57:09.58900:57:09.599 talk about like to record the USB so you 00:57:14.35900:57:14.369 can hook it to the PC for checking 00:57:16.09900:57:16.109 charting a lot of features in this one 00:57:18.20000:57:18.210 that we just don't need for this test so 00:57:24.24900:57:24.259 with that being said I hope I hope these 00:57:27.28900:57:27.299 four meters comparing gives you a little 00:57:29.53900:57:29.549 insight of the of the ESR checks and and 00:57:33.38000:57:33.390 maybe something to look for if you're 00:57:34.91000:57:34.920 interested in buying a meter or maybe 00:57:36.79900:57:36.809 you already have one looking to buy 00:57:38.24000:57:38.250 another one hopefully got a little bit 00:57:40.88000:57:40.890 out of this video today if you liked it 00:57:43.30900:57:43.319 please give it a thumbs up if you got
