Features: 1. It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery etc. 2. One button operation, automatically detect and shutdown, and you can pre the multi-functional button to close the detector too. 3. Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly. Description: It can also be used to detect infrared wave forms. It also can detect zener diode and has the function of self-calibration.
