Specification:Material: plasticDisplay: 1.8-inch TFT screenDiode range: less than 4.5vZener diode: transistor detection area: 0.01-4.5vZener diode detection area: 0.01-30vThree-terminal bidirectional SCR range: IGT less than 6mACapacitance: 25pF-100mFResistance: 0.01-50MohmInductance: 0.01mH - 20 hWeight: Approx.119g/4.2oz A full-color display multifunctional test instrument, can measure the audion, diode, resistance, capacitance, inductance, thyristor, field effect tube, regulator tube, dual diode, led, infrared decoding. Voltage measurement, built-in lithium battery, long life.Features: Self test with automatic calibration It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel, IGBT, JFET, triac and battery etc. It can also be used to detect infrared wave forms. After detection, align the infrared remote control with the "IR" 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. One button operation, automatically detect and shutdown, and you can press the multi-functional button to close the detector too. 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.
