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. 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 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 the multi-functional button to close the detector too. Put the pins of component in corresponding area, then dial 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. Display: 160*128 TFT Screen Diode Range: Less than 4.5V Zener Diode:Transistor Detect Area: 0.01-4.5V Zener Diode Detect Area: 0.01-30V Triac Range: Less than 6mA Capacitance: 25pF-100mF Resistor: 0.01-50MΩ Inductance: 0.01mH-20H Battery: 0.1-4.5V Power Mode: Rechargeable Lithium Battery(INCLUDED) Operating Instructions: 1. Multi-function key has two actions: Short : the key and not less than 10 ms, release key within 1.5 seconds Long : the key more than 1.5 seconds 2. Power on: In the power off state, short the multifunction key, the tester is turned on and automatically measured.
