- Automatically test the pins of components and display results on an LCD for clear, at-a-glance identification. - The tester can infer the prevoltage of the emitter transistor by detecting the gain factor and the transistor base, and it also detects the MOSFET protective diode and related parameters. - Fast testing: most components are tested in about 2 seconds; larger capacitors may require longer test times. - Measures MOSFET gate threshold voltage and gate capacitance for precise characterization. - Display is on a 12864 LCD (128 x 64 characters) for easy viewing in various environments. - Includes a start voltage detection function to initiate tests under appropriate conditions. - Automatically detects a wide range of components: NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes (including dual diodes), thyristors, resistors, capacitors, and other components. - Practical applications: - Electronics repair workshop: quickly identify unknown components and verify pinouts during fault diagnosis. - R&D or prototyping lab: promptly measure MOSFET gate threshold and gate capacitance for component selection. - Field service: diagnose and verify components in consumer devices, power supplies, audio equipment, and motor controllers on site.
