Notice:Do not test without dischargeDon't test online with electricityDo not hook three hooks onto the circuit board for testingDo not test live circuit boardsOtherwise, the tester will be burnt down. Burning the tester is the buyer's reason. If the repair is returned, the buyer will have to pay for it. We are not responsible for it.When the voltage and internal battery are below 3V, please charge before use.Please use 5V battery or USB port to charge.This product is only available in English and Chinese.Product DescriptionThis is a cost-effective and widely used transistor detector. Can be used to detect NPN and PNP transistors, capacitors, resistors, diodes, triodes, N-channel and P-channel MOSFETs, thyristors, batteries, etc. Can also be used to detect infrared waveforms.Features:Can be widely used to detect NPN and PNP transistors, capacitors, resistors, diodes, transistors, N-channel and P-channel MOSFETs, IGBTs, JFETs, thyristors, batteries, etc.. Zener diodes can also be detected and have a functional self-calibration.After the detection is completed, point the infrared remote control at the "IR" light, and then press the button on the remote control. If the detector decodes successfully, the data code and infrared waveform will be displayed.One-key operation, automatic detection and shutdown, you can also press the multi-function button to turn off the detector.Place the pins of the components in the corresponding area, turn the small handle, the detector will automatically detect, and the final result will be clearly displayed on the backlit TFT screen.Instead of the usual black and white display, this detector will display the results in color.Specification:Power Mode: Rechargeable Lithium BatteryDisplay: 3.5*3cm TFT screenDiode Range: < 4.5VZener diode: transistor detection area: 0.01-4.5V Zener diode detection area: 0.01-20VTriac Range: IGT < 6mACapacitance: 25pF- 100mFResistance: 0.01-50MInductance: 0.01mH-20HBattery: 0.1-4.5VProduct chip: AMTY328pPackage Included:1* Multifunctional TFT Transistor Tester1*Electronic components set1*Cable3*Test hook
