it can go to 25khz with the user selectable frequency
yes it's less than the 100khz esr meters often use
but it's enought to measure dead caps !
and far more precise to measure other caps and inductors !
I also have a small analog esr meter I build
(the one from poptronix)
and I never use it anymore...

If the OEM specifies their product at 100 KHZ, then that is the
frequency needed for a proper test.

Greetings, what is wrong with the Poptronix version..........details
anyone (I've had one as an ongoing project for awhile, I had the
bright idea a couple of years ago to put it in a probe style case with
small meter)? It also has a led for DC shorts.

there is nothing wrong with the poptronix version except that I have now
a far better esr (in fact rlc) meter since...
I still have the poptronic and it still works fine but I only have 10
leds to tell me the esr and now I have a 10000 count rlc meter...

the poptronic still has the frequency of 100khz for the test and I can
only go to 25khz with the rlc meter.
