Feature: 1. 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. 2. The tester can be used to detect infrared waveforms and Zener diodes 3. With self‑calibration function, after detection, align the infrared remote control with the "IR" light, then press the button on the remote control, if the detector successfully decodes, it will display the data code and infrared waveform 4. Simple operation, one‑key for operate, automatic detection and shutdown, you can also press the multi‑function button to close the detector 5. Place the pin of the component in the corresponding area, and then toggle the small handle, the detector will automatically test, and the result will be clearly displayed on the backlit TFT screen 6. Unlike the usual black and white display, this detector will display the color result Specification: Item Type: Transistor Tester Material: Engineering Plastic Display: 1.8 inch TFT screen Diode Range: <4.5V Zener Diode: Transistor Detection Area: 0.01-4.5V Zener Diode Detection Area: 0.01-30V Triac Switch Range: IGT <6mA Capacitance: 25pF-100mF Resistance: 0.01-50MΩ Inductance: 0.01mH-20H Battery: 0.1-4.5V Power Mode: Rechargeable lithium battery.
