I bought recently this one :

http://www.m3electronix.com/lcr.html
(the french version but it works the same)

nice kit, and with the esr meter you have for the same price of most of
esr meters kits , a precise LCR meter !!!
this is a valuable instrument I really enjoy mine ![/QUOTE]


It only has a 12.5 KHz maximum test frequecy.

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.
