This MESR-100 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.Features:It is a series resistor inside capacitor, using 100kHz to remove the impedance 1 or (2xpixFxC).The impedance become small, and we can then measure the true series resistor value.Using this theory, we can measure the capacitor is bad or 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 internal resistance of the capacitor, a printed ESR table for fast check.Equipped with a SMD alligator clip for more accurately testing. Copper plating on the surface, which is anti-corrosion and oxidation resistance.Specifications:Color: BlackRange Accuracy(After zero, Refresh Time(Manual Mode) tested with 1,10,100R Auto mode take 0 to 2s, more time resistor) depends on capacitance value.0.000 to 1.000R 1 percent and2Digit 0.4s1.000 to 10.00R 1 percent and1Digit 0.4s10.00 to 100.0R 2 percent and1Digit 0.4sAccuracy: Up to 1 percent (detail on above table)Wide Measurement Range: 1uFHigh Resolution: 4 digit, or 0.001Ohm 1 rangeMeasuring voltage: 80 HoursItem Size: Approx 14.5 x 8 x 3cm or 5.7 x 3.1 x 1.2inItem Weight: Approx 139.6g or 4.9ozPackage Size: Approx 17 x 9 x 5cm or 6.7 x 3.5 x 2.0inPackage Weight: Approx 218g or 7.7ozPackage List:1 x Capacitance Meter2 x Test Clips1 x SMD Clip1 x User ManualNote:The Capacitance Meter is used for testing the internal resistance of the capacitor, not for testing capacitance value.When shopping, please pay attention to the size and dimensions of the product to ensure that it meets your needs.
