This MESR-100 V2 auto-ranging capacitor ESR and low Ohm meter measuring range from 0.001 to 100.0R, support in circuit testing. Using true 100 KHz sine wave to measure the ESR value, which is equal to the testing method of capacitor manufacturer.

Features:
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.
Dual terminal, for fast and easy inspect general capacitor or resistor, a printed ESR table for fast check.

    With this meter you can quite easily measure electrolytic capacitors also in circuit. It gives quite nice information about electrolytic capacitors in circuit so, that you can determine and find bad capacitors from circuit without taking it out. That makes things much easier, when you are trying to find bad electrolytic capacitors from power supply and other circuits. When you find suspicious capacitor you can take it out from circuit and test it again to be sure that is it faulty or not. Great meter!
