Re: ESR meter construction question

I was just using the wires from my PCB, not the probes. I haven't tried
the resistors recently. I'll check the meter out some more this weekend.

PS What are the subscription instructions for this list? Flog me now, for
I never end up saving them. Sorry! I couldn't find them on the
flippers.com web site.

Have you tried using a jumper wire to short out the input jacks? I find the
quality of probes varies greatly...

Do you get the correct resistance values with the two test resistors? 86R
and some other resistor...
