Can be widely used to detect NPN and PNP transistors, capacitors, resistors, diodes, transistors, N-channel and P-channel MOSFETs, IGBTs, JFETs, thyristors, batteries, etc. Zener diodes can also be detected and have a functional self-calibration. After the detection is complete, point the infrared remote control at the \"IR\" light and then press the button on the remote control. If the detector decodes successfully, the data code and the infrared waveform will be displayed. One-button operation, automatic detection and shutdown, you can also press the multi-function button to turn off the detector. Place the component pins in the corresponding area, turn the small handle, the detector will automatically detect, and the final result will be clearly displayed on the backlit TFT screen. Instead of the usual display, this detector will show the results in color.
