Using 100kHz to remove the impedance 1/(2*pi*F*C), the impedance will become small, and then we can measure the true series resistor value. A bad E-capacitor have larger ESR and create large ripple rather than filtering noise. Normally, a big capacitor is larger than 3 ohm. 
Therefore, we can measure the capacitor is bad, damaged or in good condition by using this theory. 
Because this 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. Because this low testing voltage, it cannot turn on the semiconductor inside a circuit under testing. During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not.
