LCR Meter, MESR-100 ESR Capacitance Ohm Meter Professional Measuring Internal Resistance of Capacitor Capacitance Circuit Tester(MESR-100)

Dual terminal, for fast and easy inspect internal resistance of the capacitor, a printed ESR table for fast check.Note:The Capacitance Meter is used for testing the internal resistance of the capacitor, not for testing capacitance value.Specifications:Color: BlackRangeAccuracy(After zero, tested with 1,10,100R resistor)Refresh Time(Manual Mode)Auto mode take 0 to 2s, more timedepends on capacitance value.0.000 to 1.000R1%+2Digit-0.4s1.000 to 10.00R1%+1Digit-0.4s10.00 to 100.0R2%+1Digit-0.4sAccuracy: Up to 1% (detail on above table)Wide Measurement Range: >1uFHigh Resolution: 4 digit, or 0.001Ohm @ 1 range<;-40mV RMS (TESTING VOLTAGE)External Power: 5V micro USBOperating Current: 0.02ABattery: 2 * AA 1.5V Battery (not included)Battery Life time: >80 HoursItem Size: Approx 14.5 * 8 * 3cm / 5.7 * 3.1 * 1.2inItem Weight: Approx 139.6g / 4.9ozPackage Size: Approx 17 * 9 * 5cm / 6.7 * 3.5 * 2.0inPackage Weight: Approx 218g / 7.7ozPackage List:1 * Capacitance Meter2 * Test Clips1 * User Manual

• 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, etc. we can in circuit testing the capacitor is good or not.
