1. Put the pins of the component in the corresponding area, then select the small handle and the detector will test it automatically, finally the results will be clearly displayed on the backlight TFT screen. After detection, align the infrared remote control with the 'IR' light, then press the button in the remote control, if the detector successfully decrypts, it will display the data code and infrared waveform. 2.IR Decoder:Align the infrared remote control with the 'IR' light after detection, then press the button in the remote control. When the detector successfully decrypts, the data code and infrared waveform are displayed. 3.Scope of Application It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, Nchannel and P channel MOSFET, IGBT, JFET, triac and battery, etc. It can also be used to detect infrared waveforms and detect Zener diode and has the function of selfcalibration. 4.Good tool in normal life Three test sockets with short circuit, press the multifunction button, the tester will automatically calibrate. After disconnecting the short circuit according to the prompt during the calibration process, no further operations are required.
