main product Features: 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. It can also be used to detect infrared wave forms. It also can detect zener diode and has the function of self-calibration. After detection, align the infrared remote control with the "IR" light, then pre the button in the remote control, if the detector succefully decode it, it will display the data code and infrared wave form. One button operation, automatically detect and shutdown, and you can pre 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 backlight TFT screen clearly. Not like the usual black and white display, this detector will show results in color. Highlight: 1.Transistor Tester Automatic detection of zener diode 0.01-30V Self test with automatic calibration 2.IR decoder Support Hitachi IR coding IR waveform display Infrared receiving instruction 3.Other Features Measurement results using TFT graphic display(160x128) One key operation Auto Power Off(Timeout Settable) Built-in high capacity rechargeable Li-ion Battery Li-ion Battery voltage detection Support Chinese and English Specifications: Display: 160*128 TFT Screen Diode Range: < 4.5V Zener Diode:Transistor Detect Area: 0.01-4.5V Zener Diode Detect Area: 0.01-30V Triac Range: IGT < 6mA Capacitance: 25pF-100mF Resistor: 0.01-50M Inductance: 0.01mH-20H Battery: 0.1-4.5V Power Mode: Rechargeable Lithium Battery ( INCLUDED) Item Size: 8.8 x 8 x 2.8cm / 3.47 x 3.15 x 1.10in Item Weight: 111.5g / 3.94oz Operating Instructions: 1.Multi-function key has two actions: Short pre: Pre the key and not le than 10 ms, release key within 1.5 seconds Long pre: Pre the key more than 1.5 seconds 2.Power on: In the power off state, short pre the multifunction key, the tester is turned on and automatically measured. 3.Power on &measurement interface: 4.Detect transistor: In the power off state or the test is completed, put the test element into the transistor test area of test seat, and pre the locking handle, short pre the multifunction key, the tester automatically measure, graphical display of measurement results when testing is complete. Warning: Always be sure to DISCHARGE capacitors before connecting them to the tester! The tester may be damaged before you have switched it on! Warning: We do not recommend using the tester to measure the battery! The battery voltage must be le than 4.5V, otherwise the tester may be damaged!
