Default ESR meter trap

Actually the ESR meter was correct.



** The good reading was **misleading** you ****ing moron.


Actually I saw the 100 ohms and assumed that means bad.

I read too fast and thought too slow. You could have worded it
differently and I wouldn't have missed part of it.


** The Bob Parker ESR meter has an auto-ranging, two digit display that over flows above 99 ohms. It shows ESR values from 0.01 ohms to 99 ohms. The black button zeros the reading before measurements and also cycles the meter on and off.

The "good" 22uF, 500V electros showed readings close to 1.5 ohms while the "bad" ones were completely open. In reality, 2 of the 3 "good" electros were just about to fail open circuit.

Electro caps normally dry out and go high ESR fairly slowly, ones that test perfect one day and go DEAD the next are not playing fair.
