There are many different ways to test capacitors. Using a capacitance meter, using a DMM and an analog meter. In general, is it safe to assume that a capacitor is considered functional if it''s capacitance measurement is +- 20% of it''s declared value without doing the ohm/voltage test? Are these test overkill after the capacitance value has been verified?
