Default Testing capacitors


"David Looser"
"Marky P"

Is it possible to test capacitors reliably without a capacitance
meter?

If you want to test capacitors reliably you need an ESR (Effective series
resistance) meter, not a capacitance one.



** That only applies to electrolytic caps - plus the name is "equivalent
series resistance".

Plus an ESR meter will NOT find electro caps that have excessive leakage,
de-polarised or even become short circuit.

Capacitance meters are basically only handy when you have caps with no
markings, ambiguous markings or an unknown colour code.
