Features Wide application: the product can be widely used to detect NPN and PNP transistors, capacitors, resistors, diodes, transistors, N-channel and P-channel MOSFETs, IGBT, JFET, triacs and batteries. The tester can be used to detect infrared waveforms and Zener diodes Self-calibration function: with the self-calibration function after detection, align the infrared remote control to the "IR" light and then press the button on the remote control. When the detector successfully decodes, it displays the data code and infrared waveform Easy to use: easy to use, one button for operation, automatic detection and shutdown, you can also press the multifunctional button to close the detector Accurate measurement -- Place the pen of the component in the corresponding area and then press the small handle, the detector tests automatically and the result is clearly displayed on the backlit TFT screen Good service -- Our goal is to serve our customers wholeheartedly. If you have any questions, please feel free to contact us, we will reply you within 24 hours. Function: 1. Unlike the usual black and white display, this detector shows the colour result.
