Description

MESR-100 AutoRanging In Circuit ESR Capacitor Low Ohm Meter 0.001 to 100R
Descriptions: MESR-100 Autoranging capacitor ESR and Low Ohm Meter Measuring
range from 0.01 to 100.0R, support IN CIRCUIT Testing. Using true 100KHz
square wave to measure the ESR value, which is equal to the testing method of
capacitor manufacturer. In the market, there is some technique using short
pulse method to testing, but the value will be varying vs the capacitance and
sometimes reading is different from the manufacturer’s value. What is ESR of
capacitor. There is a series resistor inside capacitor, using 100kHz to remove
the impedence 1/(2piFC), the impedence 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 filering noise. Normally it is smaller
then 1 ohm. Using this theory, we can measure the capacitor is bad/ damaged or
good in condition. Because our ESR meter only apply less than 15mV DC or pk to
pk on a good capacitor, so we can use it as in circuit test. Because this low
voltage, it can not 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. Dual terminal, for fast and easy inspect general
capacitor or resistor, a printed ESR table for fast check Range Accuracy
