Great video - question. How did you fix your MESR-100 tester when you tested a charged cap? I just did it and it's not working now. Any help would be appreciated. Thanks.
I replaced a diode that had blown. Let me know if you can't figure out which one and I will open my meter and look, maybe it will jog my memory. I think it was pretty obvious in my case.
I've found that the DER DE-5000 LCR meter is a much better choice than the GME in that price range. I've had great success with it, and its in-circuit ESR performance is quite good. A recommended improvement for the DER is to make your own Kelvin test clips for the unit. A good test for it was a subwoofer amp that had 12 out of its 16 electrolytics gone to the dark side. All 12 read bad both in-circuit and out-of-circuit. Accurate in-circuit ESR testing is extremely useful. The unit is also excellent for testing inductors, and of course resistors. One MUST DISCHARGE THE CAP first. Beyond safety for the unit, a small charge left on a cap can confuse an ESR/C meter.
@@StuartPatterson Your certainly welcome, and thanks for this video. Just wanted to add a note that there are a few videos on YT about how to fashion your own Kelvin clips for the DE-5000. It's worth the effort and additional expense for the additional accuracy and convenience.
Great tutorial. You can also test the resistance and microhenries of the inductors with the esr meter. The reactance formula is 2𝛑FL. That would be 2 x 3.14i x frequency of esr meter x 100 (uH) Just plug it in. R=0.628 X L(uH) L(uH)=R(ohms)/0.628
@@StuartPatterson Even $50 is too much for something relatively simple. I think it's priced as such only because it's much less in demand than DMMs, hence less competition.
Thanks for review. Very good 👍❤
Thanks for watching!
Useful demonstration.
Thank you!
Are ceramic capacitors treated any differently than electrolytic caps as far as testing ESR?
It is my understanding that ceramic caps can still suffer from issues with ESR but it is extremely rare when compared to electrolytics.

I have the same issue. A cap damaged it.
I have seen a video that the TC1 type meters need to be calibrated before use.have you done that?
Good question. I have never calibrated one before and have not looked inside one to see how it could be done. Maybe I should.
Can you do a comparison between Antek blue ear vs this one ? How close are the readings ( out of circuit & in circuit )
That is a great idea but I don’t currently own the Anatek Blue ESR meter. If that changes in the future I will certainly compare them.

Thanks! I need to checkout the DE-5000. The price is certainly good!

Thanks!
Interesting how the the 3rd one is obviously subpar to MESR, and yet more than twice the price... Who would pay for that?!?
Always better to research test equipment before buying it!

@@DrN007 Makes sense. Love your username!
@@StuartPatterson Thanks man :)
