Our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result we can use it as in circuit test. Using this theory, 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. During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not.

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