Product Description
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/(2*pi*F*C), 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/(2*pi*F*C).
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.
