Using this, we can measure the capacitor is bad/ damaged or good in condition.

The impedance become small, and we can then measure the true series resistor value.

It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C).

Our ESR meter only applies less than 15mV DC or on a good capacitor, as a result we can use it as in circuit test.

If our products have any problems, we can provide replacement / Return Service, welcome to contact us anytime!
