After the detection is completed, 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 infrared waveform be displayed. Place the pins of the components in the corresponding area, turn the small handle, the detector automatically detect, and the final result be clearly displayed on the backlit TFT screen. One-key operation, automatic detection and shutdown, you can also press the multi-function button to turn off the detector. 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. Instead of the usual black and white display, this detector display the results in color., Manufacturer: Littimoon
