Description : For detecting NPN and PNP transistor , capacitor , resistor , diode , triode , N - channel and P - channel MOSFET , IGBT , JFET , triac and battery , resistor and capacitor and other components , etc . 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 screen clearly . After detection , align the infrared remote control with the & quot ; IR & quot ; light , then press the button in the remote control , if the detector successfully decode it , it will display the data code and infrared wave form . Easy and convenient to use and operate . One key operation , Auto Power Off - One button operation , automatically detect and shutdown . Specification : Display : 1 . 8 inchTFT Screen Diode Range : & lt ; 4 . 5V Diode : Transistor Detect Area : 0 . 01 - 4 . 5V Diode Detect Area : 0 . 01 - 30V Triac Range : IGT & lt ; 6mA Capacitance : 25pF - 100mF Resistor : 0 . 01 - 50M Inductance : 0 . 01mH - 20H Battery : 0 . 1 - 4 . 5V Power : Rechargeable Lithium Battery ( INCLUDED ) Size Chart : Size : Approx . 9x7cm / 3 . 54x2 . 76inch Package Includes : 1 Piece Transistor Tester : Please allow 1 - 3mm measuring deviation due to manual measurement . Due to the different monitor and light effect , the actual color of the item might be slightly different from the color showed on the pictures .
