Features:128*160 TFT color display for easy readings, can display measured data and graphics.Powered by 9V battery(not included).All components are protected by a plastic case, convenient to carry.Automatically detect NPN and PNP transistors, N-channel and P-channel MOSFET, diodes, thyristors, resistors, capacitors or other devices.Automatically test the pins of a component and display on the LCD.Measure the gate threshold voltage and gate capacitance of the MOSFET.Measure bipolar transistor current amplification factor and base-emitter threshold voltage.Two-button operation, automatic shutdown to avoid unnecessary waste.Short detection time: only 2 seconds. It is normal to cost 1 minute for bulk capacitor detection.Note:Please make sure that capacitors are discharged before testing.
