Features: -controller using 8MHz external crystal, better measurement accuracy. utomatically detect NPN, PNP bipolar transistors, N-channel and P-channel MOS FET, JFET, diodes, dual diode, thyristor small power Key resistance using a thousandth of a metal film resistors, the remaining a hundredth metal film resistors. unidirectional and bidirectional thyristor. One button operation, automatic shutdown with only 20nA shutdown current. Each test takes about two seconds, with only capacitors and inductance measurements taking . Can be in correct order and the diode symbol display two diodes, and gives the diode forward voltage. LCD backlit LCD screen with low power consumption, compared with the whole power consumption is almost negligible, so the light is always there, easy reading in the dark. Specifications: Shutdown Current: 20nA Resistance Measurement: Max. 50M Resistance Resolution: 0.1 Capacitance Measurement: 30pF~100mF Capacitance Resolution: 1pF Inductance Measurement: 0.01mH-20H Size: . 123 x 80 x 33mm / 4.84 x 3.15 x 1.3in Technical performance: 1. Automatic recognition transistor type, pin, current magnification and the base - emitter junction voltage measured at the same time. 2. Automatic Identification of N and P MOSFET type and pin,measure the voltage and capacitance. 3. Automatic identification the diode pin, measurement the forward voltage. 4. Automatic identification of small power triac pin. 5. Measuring resistance. 6. Measuring inductance. 7. Measuring Capacitance. 8. One button operation, automatic shutdown. 9. 20nA current shutdown is only about. 10. Using 8MH crystals. 11. Can automatically detect NPN, PNP bipolar transistors, N-channel and P-channel MOS FET, JFET, diodes, dual diode, thyristor small power unidirectional and bidirectional thyristor. Note: Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter. Color: As Shown Material: plastic Package Contents: 1 x Capacitance Tester Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
