Description: For detecting NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery, resistor and capacitor and other components, etc. 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 for TFT screen clearly. After detection, for align the infrared remote control with the inchIR inch light, then press the button in the remote control, if the detector successfully decode it, it will display the data code and infrared wave form. Easy and convenient to use and operate. One key operation, Auto Power Off-One button operation, automatically detect and shutdown.
