Fast and efficient testing - Most components are tested in about 2 seconds. Large capacitors may take longer, which is normal. MOSFET gate measurement - Measures MOSFET gate threshold voltage and gate capacitance. - Results are displayed on a 128x64 LCD (128 x 64 characters). Automatic component detection - Start voltage detection feature with automatic identification of components: NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes (including dual diodes), thyristors, resistors, capacitors and other components. Automatic pin testing and display - Pins are tested automatically and results shown on the LCD. - It can determine the emitter transistor positive bias by detecting the gain factor and the base, and identify the MOSFET protective diode, etc. Use scenarios - In repair shops, quickly verify components on power supplies and audio boards to speed up diagnosis. - In development labs, evaluate MOSFETs, transistors and diodes during prototyping and debugging. - In field service, carry a portable tester to confirm component integrity on various consumer electronics boards.
