1. Easy to Use: Insert the pins of the component into the corresponding areas, then select the small handle and let the detector test automatically. The results are clearly displayed on the backlight TFT screen. After detection, align the infrared remote control with the IR light and press a button on the remote; if the detector decrypts successfully, it will display the data code and the infrared waveform. 2. IR Decoder: Align the infrared remote control with the IR light after detection, then press a button on the remote. When the detector decrypts successfully, the data code and infrared waveform are displayed. 3. Scope of Application: This tester can be widely used to detect NPN and PNP transistors, capacitors, resistors, diodes, triodes, N-channel and P-channel MOSFETs, IGBT, JFET, triac and batteries, etc. It can also be used to detect infrared waveforms and to detect Zener diodes, with self-calibration functionality. 4. Good tool in normal life: Three test sockets with short circuit capability. Press the multi-function button to automatically calibrate. After disconnecting the short circuit according to the prompt during calibration, no further operations are required.
