Features 【Auto Detection for Multiple Components】: This multifunction tester automatically detects NPN/PNP transistors, MOSFETs, diodes, thyristors, resistors, and capacitors, making it a versatile tool for electronics enthusiasts and professionals. 【12864 LCD Graphical Display】: Featuring a 12864 LCD display with backlight, this capacitor esr meter provides clear and detailed readings for transistors, capacitors, inductors, and ESR values, ensuring accurate diagnostics. 【One-Key operations & Auto Power Off】: Designed for ease of use, this transistor tester features one-key operations and an auto power-off function with a shutdown current of only 20nA, saving battery life and energy. 【Wide Measurement Range】: Capable of measuring (0.1Ω-50MΩ), capacitance (25pF-100mF), inductance (0.01mH-20H), and ESR values, this lcd graphical tester is ideal for comprehensive electronic component testing. 【Portable & Battery-Powered】: Powered by a 9V battery, this portable auto detection tester is compact and lightweight, making it for on-the-go use in workshops, labs, or field repairs. Specification: This graphical multi function tester iscomposed of + capacitance + diode + inductor + transistor +mos. LCD12864 LCD display, with a backlight, backlight color is generally yellow green.Power supply for 9V stacked battery. If for long time power supply, it can use2 lithium battery composition of 8.4v battery as power supply. Function: *Added boot voltage detection function. *Automatic detection of NPN and PNPtransistors, N channel and P channel MOSFET, diodes (including dual diode),thyristor, transistors, resistors and capacitors and other components. *Automatically test the pin of the elementand display it on the LCD. *The positive bias voltage of the emittertransistor can be determined by detecting the amplification factor and the baseof the transistor, the MOSFET protections diode, etc. *Measurement of gate threshold voltage andgate capacitance of MOSFET. *Display using 12864 LCD LCD (128*64characters). *Higher test speed, effective componenttest: in 2 seconds (except for the larger capacitor, the measurement of largecapacitance also takes a long time to measure the time for 1 minutes isnormal). *One key operations, power on to test, one key toget the work done. *Power consumption off mode: less than 20nA *Automatic shutdown function can avoidunnecessary waste, save battery energy, improve the life time.
