Function: 1. The product can be widely used to detect NPN and PNP transistors, capacitors, resistors, diodes, transistors, N-channel and P-channel MOSFETs, IGBTs, JFETs, triacs and batteries. 2. The tester can be used to detect infrared and zener diode waveforms 3. With auto-calibration function, after detection, set the infrared remote control with "IR" light, then press the button on the remote control, if the detector successfully decode, it will display the data code and infrared waveform 4. Simple operation, one key to operate, automatic detection and shutdown, you can also press the multi-function button to close the detector 5. Put the component pin in the corresponding area, then switch the small handle, the detector will automatically test, and the result will be clearly displayed on the TFT backlit screen 6. Unlike the usual black and white display, this detector will display the result in color Specification: Item Type: Transistor Tester Material: engineering plastic Display: 3.5 inch TFT screen Diode Range: <4.5V Zener diode: Transistor sensing area: 0.01-4.5V Zener diode detection area: 0.01-30V Triac switching range: IGT <6mA Capacitance: 25pF-100mF Resistance: 0.01-50MΩ Inductance: 0.01mH-20H Battery: 0.1-4.5V Power Mode: Rechargeable Lithium Battery Package List: 1 x Tester 3 x connection cable 1 x LED 1 x capacity 1 x 3-pin 1 x charging cable
