Features Widely applicable for detecting NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac, and battery, etc. Can also detect zener diode and has a self-calibration function. After detection, align the infrared remote control with the IR light, then press the button on the remote control. If the detector successfully decodes, it will display the data code and infrared waveform. One-button operation, automatic detection, and shutdown. You can press the multi-function button to turn off the detector. Insert the pin of the component into the corresponding area, power on the detector, the detector will test automatically, and finally display the results on the backlit TFT screen clearly. Unlike the usual black and white screen, this detector displays results in color.
