It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, and battery etc. It can also be used to detect infrared wave forms. It also can detect zener diode and has the function of self-calibration. After detection, align the infrared remote control with the "IR" light, then press the button in the remote control, if the detector successfully decode it, it display the data code and infrared wave form. One button operation, automatically detect and shutdown, and you can press the multi-functional button to close the detector too. Put the pins of component in corresponding area, then the little handle and the detector test it automatically, finally the results display on the backlight TFT screen clearly. Not like the usual black and white display, this detector show results in color., Manufacturer: Akfldms
