Re discharging capacitors. Earlier this year I got some JCCON brand caps from Ali for a power supply board. After testing the finished board, it sat there for around a month before I started doing something with it. I placed it on my bench top next to a metal key chain and at some point, I pushed it against the key chain and got a massive spark as it shorted out. Aside from the scare, I thought they must be pretty decent caps to hold a charge that long.
Nice review but I don’t think this one measures ESR for that you’d need the Peak ESR70 which I use. I have a couple of Peak meters and they aren’t cheap but are accurate and work well (unlike the Chinese junk meters I had before).
Good meters from China are great for hobbyists because of their low cost & they generally are accurate. Industry uses Fluke to make batch calibration & certification easier as they are standardized in industrial usage. I have a Kaiweets KM601 that generally work well at home. Once in awhile it does not boot properly & I just have to restart it. It is very accurate, but this is the kind of meter that you should not measure high voltage with. The circuit board layout & protection is better on the Fluke, but most homeowners do not measure high voltage. My workplace uses Fluke, but while knowing the limitations, a good meter from China is OK for home.
I bought the Kaiweets after seeing your video and I have found it to be really great
Hope you enjoy it!
Thanks for the review. I saw you talk about them but lost track of it.
Cheers Steph, appreciated.

I got the Peak Atlas "Duo" (DCA Pro+LCR45) with the plastic case, I never use them yet but those UK made tools have great reviews and good supports.
I use a DER DE-5000 LCR meter and find it really good.

I stand corrected. You are right this one doesn't measure ESR. It does measure impedance, admittance and mag/phase of caps.
Out of topic...FM Acoustic 300A amplifier .SS that sound like tubes !Just purchased one !
Cool!
Hi, how is your tinnitus?
Much better, still there and varies but much better most days.

It is not wise to short out capacitors to discharge them,it could cause some damage.I use a 8ohm 5 watt resistor to discharge.
I was referring to possible 2-3 volts they might have stored in them.
