This versatile tester automatically detects NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes (including dual diodes), thyristors, transistors, resistors, capacitors, and other components. It automatically tests the pins of a component and displays them on the LCD screen. Detects transistor, MOSFET protection diode's amplification coefficient, and the base to determine the emitter transistor's forward bias voltage. Measures gate and gate capacitance of MOSFET threshold voltage. Simultaneously measures two resistors and displays the resistor symbol. Measures the reverse capacitance of a single diode. Displays two diodes in the correct order with the diode symbol and provides the diode forward voltage. Measures capacitance from 30pF-100mF with 1pF resolution. Obtains the connection of the rectifier bridge with a single measurement. Note: Before measuring capacitance, the capacitor must be discharged, otherwise the meter is very likely to be damaged. One-button operation, automatic shutdown. Only 20nA shutdown current. Automatic identification of component pin arrangement. Measures bipolar transistor current amplification factor and base-emitter threshold voltage. Identifies transistors via the base-emitter threshold voltage and high current amplification factor. Measures gate-MOS FET threshold voltage and gate capacitance. Reverse breakdown voltage is less than 4.5V, Zener diode can be identified. 128x64 large backlit LCD screen, only 2mA in standby. Test Range: Inductors, capacitors, diodes, dual diode, mos, transistor, SCR, regulator, LED tube, ESR, resistor, adjustable potentiometer. Resistance: 0.1 ohm resolution, maximum 50M ohm.
