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.
