Large and clear LCD digital display: This amazing detector uses a 1.8" high-resolution TFT color LCD display. Different parameters display different colors, convenient and simple. Automatic identification: The intelligent transistor detector automatically detects NPN and PNP transistors, N-channel and P-channel transistors, diodes, thyristors, resistors, capacitors or other devices. Battery powered. Automatic shutdown function: It has an automatic shutdown function. The shutdown countdown is displayed on the screen, and the shutdown countdown can be extended to 40 seconds. Wide application: This multi-function capacitance meter can be used to test triodes, field-effect transistors (FETs), diodes, resistors, capacitors, inductors, MOS, SCR, and can be used for various transistor tests electronics.
