1.[Large and Clear LCD Digital Display]: This amazing detector uses a 1.8' TFT color LCD screen with high resolution. Different parameters display different colors, convenient and simple. 2.[Automatic Identification]: The DROK smart transistor detector automatically detects NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes, thyristors, resistors, capacitors or other devices. 3.[Auto-shutdown Function]: It has an auto-shutdown function. The shutdown countdown is displayed on the display, and the shutdown countdown can be extended to 40 seconds. 4.[Wide Application]: This multi-function capacitance meter can be used to test triodes, field effect transistors (FET), diodes, resistors, capacitors, inductors, MOS, SCR, and can be used for various electronic transistor tests.
