Feature:1. WIDE COMPATIBILITY: Transistor meter can be widely used to test NPN and PNP transistors, capacitors, resistors, diodes, triodes, N channel and P channel MOSFETs, IGBTs, JFETs, 3 terminal bidirectional SCR switches, and batteries.2. INFRARED REMOTE CONTROL DECODING: After testing, simply point the infrared remote control towards the IR light, press a button on the remote control, and if the detector successfully decodes, it will display the data code and infrared waveform.3. 1 BUTTON OPERATION AND AUTOMATIC SHUTDOWN: Easy to use with 1 button operation for automatic testing and shutdown. The detector can also be manually turned off using the multifunction button.4. EASY TESTING PROCESS: Place the pins of the component in the corresponding area, then turn the small knob, and the detector will automatically test. The final results will be clearly displayed on the backlit LCD screen.5. CONVENIENT AND RELIABLE: Provides accurate and reliable testing results, the ESR tester is a valuable tool for electronic enthusiasts and professionals in troubleshooting and component analysis.Specification:Item Type: Transistor MeterMaterial: PCBDiode Range: <4.5VZener Diode: Transistor Detection Area: 0.01-4.5VTriac Range: IGT<6mACapacitance: 25pF-100mFResistor: 0.01-50MInductance: 0.01mH-20HPower Mode: Lithium battery x 1 (200mah) (shipped with built in battery).Package List:1 x Transistor Meter1 x USB Charging Cable 3 x Accessory 1 x Test Clip
