Measuring Resistance,MESR-100 ESR Capacitor Tester Ohm Meter Professional Measuring Internal Resistance of Capacitor Capacitance Circuit Tester Capacitor Meter with SMD Test Clip
$57.99
Description
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 in condition..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..During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not.
