Self-Calibration: Features a self-calibration function. After detection, align the infrared remote control with the "IR" indicator, then press the remote button. If the detector successfully decodes, it will display the data code and infrared waveform. Advantage: Compared to standard black and white displays, this detector shows results in color. The tester can be used to detect infrared waves and Zener waveforms. Simple Operation: Easy to use with a single button for operation, automatic detection, and the ability to turn off the detector by pressing the multi-function button. Component Support: Use the component shaft in the corresponding area, then tilt the small handle. The detector will provide a clear result displayed on the Retro-Blushed TFT screen. Wide Application: The transistor tester can be widely used to detect NPN and PNP transistors, capacitors, resistors, diodes, transistors, N-channel and P-channel MOSFETs, IGBTs, JFETs, TRIACs, and batteries.
