MESR-100 V2 Low Ohm Meter and Capacitance Tester

The accuracy of the Range (After refresh time, manually tested with 1, 10, 100R taking 0 to 2s, more time resistor) depends on the capacitance value. The accuracy ranges from 0.000 to 1.000R with 1%+2Digits and a refresh time of -0.4s, 1.000 to 10.00R with 1%+1Digit and a refresh time of -0.4s, and 10.00 to 100.0R with 2%+1Digit and a refresh time of -0.4s. The accuracy is up to 1% based on the table provided.

The capacitance meter has a wide measurement range of up to 1uF, high resolution of 4 digits or 0.001Ohm @ 1Ω range, and measures less than -40mV (testing) externally with 5V Mini USB operating current of 0.02A. It requires 2 AA 1.5V batteries (not included) with a battery life of 80 hours. The size of the meter is 14.58*3cm and is made of ABS + electronic components in black color.

The contents include 1 capacitance meter, 2 test items, and 1 manual.

Note: Light and different displays may affect the color of the item, and the measurement allowed error is +/- 1-3cm. The meter only applies to less than 15mV DC or on a good capacitor when used for in-circuit testing.

1. There is a series resistor inside the capacitor, using 100kHz to remove the impedance 1/(2*FC).
2. The impedance becomes small, and then measure the true series resistor value. Using this, measure if the capacitor is damaged or in good condition.
3. During repairing TV, LCD, Audio board, etc., in circuit testing the capacitor to see if it is in good condition.
4. Terminal, for fast and easy inspection of general capacitors or resistors, is available in a table for fast checking.
