SELF-CALIBRATIONWith self-calibration function, after detection, align the infrared remote control with the "IR" indicator light, then press the button on the remote control, if the detector decodes successfully, it will display the data code and infrared waveform ADVANTAGEUnlike the usual black and white display, this detector will display the color result. The tester can be used to detect infrared waveforms and Zener diodes SIMPLE OPERATIONSimple operation, one key to operate, automatic detection and shutdown, you can also press the multi-function button to close the detector USAGEPlace the component pin in the corresponding area, then toggle the small handle, the detector will automatically test, and the result will be clearly displayed on the backlit TFT screen WIDE APPLICATIONThe 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.
