This MESR-100 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.

Note:
The Capacitance Meter is used for testing the internal resistance of the capacitor, not for testing capacitance value.
