Re: Capacitor testing
No,,, and yes,,,, mostly no.
ESR is a frequency related thing.
The device is called and ESR meter.
It's basically the same as a DMM but the voltage sent to check resistance is AC at around 100kHz.
-
DMM can be used to find shorted caps which an ESR meter won't tell you for sure.

Been around a while.
Bob Parker, the guy that designed it upmteen years ago, is a member here.
I just built one from the kit version. Nice little meter.
This is a new one based on the same design.

I heard about it like TWO DAYS after I bought mine of I may have gotten it instead.
They are both the same electronically.
The one I have uses 6 AAA batts and is room for some mods.
(There are mods/upgrades out for them. I did a couple of them.)
-
The new one uses a 9V but I doubt there is room for some of the mods.
