Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si 1.It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C). 2.The impedance become small, and we can then measure the true series resistor value.,Using this , we can measure the capacitor is bad/ damaged or good in condition. 3.Our meter only applies less than 15mV DC or to on a good capacitor, as a result we can it as in circuit test. 4.During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not. 5. Dual terminal, for fast and easy inspect general capacitor or resistor, a printed table for fast check. Range Accuracy(After , 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%+2Digit -0.4s 1.000 to 10.00R 1%+1Digit -0.4s 10.00 to 100.0R 2%+1Digit -0.4s Accuracy: Up to 1% (detail on above table) Wide Measurement Range: Greater than 1uF High Resolution: 4 digit, or 0.001Ohm @ 1 range Measuring voltage: Less than -40mV (TESTING VOLTAGE) External : 5V Mini USB Operating Current: 0.02A Battery: 2 * AA 1.5V Battery (not included) Battery Life time: Greater than 80 Hours size:14.5 * 8 * 3cm Material:ABS + electronic components colour:black Package Contents: 1 * Capacitance Meter 2 * Test Clips 1 * User Manual Only the above package content, other products are not included.
