1、Automatic detection of NPN and PNP transistors, N‑channel and P‑channel MOSFETs, diodes (including double diodes), thyristors, triodes, resistors and capacitors. Automatically test component leads and display them on LCD. 2、The forward bias voltage of the transmitting transistor can be determined by the amplification factor and base number of the detection transistor, MOSFET protection diode, etc. 3、Fast test speed, effective component test within 2 seconds (except for larger capacitors, large capacitance measurement also takes a long time, the measurement time within 1 minute is normal). 4、Supports automatic shutdown function, which can avoid unnecessary waste, save battery power and extend battery life. 5、Support boot voltage detection function, support measurement of gate threshold voltage and gate capacitance MOSFET Condition: 100% Brand New Item Type: Transistor Tester Material: Fiberglass Color: As the Picture Shown Size: Approx. 7.3 x 6 x 1.3cm/2.9 x 2.4 x 0.5in Resistors: 0.1[-50M] Capacitance: 25pF-100000uF Inductance: 0.01mH-20H Working Power: DC-9V Standby Current: 0.02uA Working Current: 25mA 1 x Transistor Tester
