It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery etc<br>It can also be used to detect infrared wave forms. It also can detect zener diode and has the function of self-calibration<br>After detection, align the infrared remote control with the "IR" light, then press the button in the remote control, if the detector successfully decode it, it will display the data code and infrared wave form<br>One button operation, automatically detect and shutdown, and you can press the multi-functional button to close the detector too<br>Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly<br><br>Not like the usual black and white display, this detector will show results in color<br>Note: The electronic component package is random and cannot be<br>Material:ABS<br>colour:White<br><br>Package Contents:<br>1 x Multi-function transistor tester<br>1 x Electronic component set<br>1 x cable<br><br>Only the above package content, other products are not included.<br>Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
