It can be widely used to detect NPN and PNP transistors, capacitors, resistors, diodes, triodes, N-channel MOSFETs and P-channel MOSFETs, IGBTs, JFETs, TRIACs, and batteries. It can also detect Zener diodes and features an automatic calibration function. Infrared light, then press the remote control button. If the detector successfully decodes, the data code and infrared waveform will be displayed. One-button operation, automatic detection and stop, and you can press the multifunction button to turn off the detector as well. Place the component pins into the appropriate area, then assemble the small handle, and the detector will automatically test. The results are clearly displayed on the TFT screen. Unlike ordinary black and white characters, this detector displays color results. Display: 1.8-inch TFT screen, color display Diode Range: less than 4.5V Zener Diode: Transistor detection range: 0.01 to 4.5V Zener Diode detection range: 0.01-30V Triac Range: Igt less than 6mA Capacitance: 25pf-100mf Resistance: 0.01 to 50 mΩ Inductance: 0.01 MH-20H Power Voltage: 3.7V Note: All data is measured manually; please allow for a 1 to 3 cm error due to light differences and display. There may be color differences; please refer to the actual item received.
