Usage Tips: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 then measure the true series resistor value.,Using this , 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 use it as in circuit test. 4.During repairing TV, LCD, Audio board, etc. 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 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%+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: 1uF High Resolution: 4 digit, or 0.001Ohm @ 1 Ω range Measuring voltage: Less than -40mV RMS (TESTING VOLTAGE) External Power: 5V Mini USB Operating Current: 0.02A Battery: 2 * AA 1.5V Battery (not included) Battery Life time: 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.
