Determining the Equivalent Series Resistance (ESR) of Capacitors
However, if there are hundreds of capacitors, it is tedious to remove each capacitor, and there is an increased risk of damaging the capacitors or the circuit board during the removal. A typical ESR meter uses a high-frequency current of about 100 kHz and a low voltage of about 250 mV or less.
