This Signstek MESR-100 V2 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. Using 100kHz to remove the
impedance 1/(2piFC), the impedance will become small, and then we can
measure the true series resistor value. A bad E-capacitor have larger ESR and
create large ripple rather than filtering noise. Normally, a big capacitor is
larger than 3 ohm. Therefore, we can measure the capacitor is bad, damaged or
in good condition by using this theory. 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. Advantage
of V2: 1) Change square wave to sine wave 100 KHz, reduce square wave’s high
frequency component, and affect the reading passing the test leads and
capacitor. 2)Higher Resolution up to 0.001 ohm. 3)128X64 dot matrix LCD, with
larger value display and information 4)Embedded 25V capacitor table at LCD,
auto display the capacitor is good or bad reference to common 25V electrolytic
capacitor. 5)New plastic case, curve design for hand carrying. New stand for
60 degree stand on desk. 6)Use 2X AA battery, more convenience and longer
battery life than 9V battery. 7)Support external USB power, using standard
micro-USB port. Features: It is a series resistor inside capacitor, using
100kHz to remove the impedance 1/(2piFC). The impedance become small, and
we can then measure the true series resistor value. Using this theory, we can
measure the capacitor is bad/ damaged or good in condition. 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. 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. Specification: 1)Accuracy: Up to 1% (detail on above table) 2) High
