It can also detect Zener diodes and self calibration function. After detection, align the infrared remote control with the infrared light and press the button on the remote control. If the detector successfully decodes, it display the data code and infrared waveform. One click operation, automatic detection and stop, you can also press the multifunction button to turn off the detector. It can be widely used to detect transistors, capacitors, resistors, diodes, transistors, MOSFETs N-channel and P-channel IGBT,JFET, Three terminal bidirectional thyristor switch and NPN and PNP batteries. Place the pins of the component in the appropriate area and mark the small handle. The detector automatically check and the results be clearly displayed on the TFT screen. Unlike the usual black and white display of characters, this detector display color results., Weight: 0.2314853751 Pounds, Manufacturer: Xnuiasqe
