Features One-key operation, power-on test, one-key operation, MOSFET gate threshold voltage and gate capacitance measurement. Detects transistor emitter forward bias voltage, MOSFET protection diode, and amplification factor reference. Large LCD display with backlight for easy reading. Pin components are automatically tested and displayed on the LCD. Automatic detection of NPN, PNP bipolar transistors, N-channel and P-channel MOSFETs, diodes (including dual diodes), thyristors, transistors, resistors and capacitors. This meter is a small tool for the engineer, electronic maintenance and factory. It is very easy to test plug-in and SMD devices, also can test different kinds of diodes, triodes, thyristors, MOSFET, enable to analysis the device type, the polarity of the pin, the output HFE, the valve voltage, the junction capacitance of the FET.
