Mulcort Capacitor Tester Ohm Meter Professional Measuring Internal Resistance of Capacitor Capacitance Circuit Tester Capacitor Meter with SMD Test Clip
It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C). The impedance become small, and we can then measure the true series resistor value. Using this theory, we can measure the capacitor is bad/ damaged or good...
