Features:

  • Digital LCD display for easy readings, can display measured data and graphics.

  • Rotary switch control, a key measurement for convenient use.

  • Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.

  • Use 9V battery(not included), can also use DC power(DC 6.8-12V).

  • Automatic shutdown, shutdown current is only about 20nA.

  • Automatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout.

  • Test NPN and PNP transistor common-emitter current amplification factor, the base-emitter threshold voltage, off the collector - emitter leakage current.

  • Support 2 resistors measurement, show its positive and negative, on-state voltage.

  • Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ.

  • Automatically test the pins of a component and show on the display.

  • Measure FET gate threshold voltage and gate capacitance.

  • For the following 2100Ω resistor while measuring its inductance measuring range from 0.01mH - 20H.

  • Can be used as signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM(pulse width modulation) signals.
