The MESR-100 ESR auto-ranging capacitor and low-ohm meter measures from 0.001 to 100.0R and is compatible with circuit testing. Measure the ESR value using a 100kHz true sine wave,

Same testing method as the capacitor manufacturer. Features: It is a resistor connected in series inside the capacitor
, which uses 100 kHz to eliminate impedance 1/ (2* pi* f* c).
Using this theory we can measure whether the capacitor is faulty/damaged or in good condition.
Our ESR meter only applies less than 15mV DC voltage, or peak-to-peak, on a good capacitor, so we can use it as a circuit test.
When repairing TVs, LCD screens, sound cards, etc. we can test whether the capacitors in the circuit are good.
Dual terminals for quick and easy checking of capacitor internal resistance, printed ESR meter for quick verification.

notes:
The capacitance meter is used to test the internal resistance of the capacitor, not the capacitance value.
