Description :
MESR-100 AutoRanging ESR Low Ohm Circuit Capacitor Meter Tester
Feature :
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.
What is ESR of capacitor?
There 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.
A bad E-capacitor will have larger ESR and create large ripple rather than filtering
noise. Normally, a big capacitor is larger than 3 ohm.
Using this theory, we can measure the capacitor is bad/ damaged or good in condition.
Because 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. Because this low testing voltage, it
cannot turn on the semiconductor inside a circuit under testing.
During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is
good or not.
