1. It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery etc.2. One button operation, automatically detect and shutdown, and you can press the multi-functional button to close the detector too.3. Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly.Display: 1.8 inch TFT ScreenDiode Range: less than 4.5VZener Diode : Transistor Detect Area: 0.01-4.5V Zener Diode Detect Area: 0.01-30VTriac Range: IGT less than 6mACapacitance: 25pF-100mFResistor: 0.01-50M ohmInductance: 0.01mH-20HBattery: 0.1-4.5V Mode: Rechargeable Lithium Battery (Include)Size: Approx. 90 x 50 x 25mmcolour: as shownMaterial: plasticPackage Contents:1 x Multi-functional TFT Transistor tester1 x Electronic component set(random colors style, don't accept the specified color style)3 x Test hooks1 x CableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
