ESR meter built in seconds
** Connection of the scope direct to the electro cap is important.
Otherwise, the inductive reactance of the cable from the generator
( at 100kHz ) to the cap becomes included in the scope display of
ESR - and is often more than the ESR of a good cap.
Thanks for the clarification. I suspected something like that, but didn't
consider the cable's self-inductance would be significant at 100kHz.
