Features:_x000D_ It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C)._x000D_ The impedance become small, and we can then measure the true series resistor value._x000D_ Using this theory, we can measure the capacitor is bad/ damaged or good in condition._x000D_ 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._x000D_ During repairing TV, LCD, o board, etc. we can in circuit testing the capacitor is good or not._x000D_ Dual terminal, for fast and easy inspect internal resistance of the capacitor, a printed ESR table for fast check._x000D_ Note:_x000D_ The Capacitance Meter is used for testing the internal resistance of the capacitor, not for testing capacitance value._x000D_ Specifications:_x000D_ Color: Black RangeAccuracy (After zero, tested with 1,10,100R resistor)Refresh Time(Manual Mode) Auto mode take 0 to 2s, more timedepends on capacitance value._x000D_ 0.000 to 1.000R1%+2Digit0.4s_x000D_ 1.000 to 10.00R1%+1Digit0.4s_x000D_ 10.00 to 100.0R2%+1Digit0.4s_x000D_ Accuracy: Up to 1% (detail on above table)_x000D_ Wide Measurement Range: >1uF_x000D_ High Resolution: 4 digit, or 0.001Ohm @ 1 range_x000D_ Measuring voltage: 80 Hours_x000D_ Item Size: Approx 14.5 * 8 * 3cm / 5.7 * 3.1 * 1.2in_x000D_ Item Weight: Approx 139.6g / 4.9oz_x000D_ Package Size: Approx 17 * 9 * 5cm / 6.7 * 3.5 * 2.0in_x000D_ Package Weight: Approx 218g / 7.7oz_x000D_ Package List:_x000D_ 1 * Capacitance Meter_x000D_ 2 * Test Clips_x000D_ 1 * User Manual
