Test capacitors without an ESR meter?

Buy or make a cheap Chinese AVR tester if you need something to get you by.
Then later a Bob Parker designed ESR meter with input protection mod for frequent in circuit testing. Then a DER EE DE5000 LCR meter for out of circuit testing at different frequencies.

FWIW the link @bitseeker posted was what led me to order one. After a $20 DMM, I think it's the best investment you can make.

And not to be forgotten, if you have an analog panel meter lying around, build the 5-transistor ESR meter:

If you want to use a multimeter as the display use Jay_Diddy_Bs other design.
