Lcd Gm328 Transistor Tester Esr Voltage Frequency Meter

Features:

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.Rotary switch control, a key measurement for convenient use.
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 0.01?, can be measured up to 50M?.
Measure FET gate threshold voltage and gate capacitance.Automatically test the pins of a component and show on the display.Digital LCD display for easy readings, can display measured data and ie.
For the following 2100? 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.

Notice:

Before measuring capacitance, the capacitor must be discharged, otherwise very likely dae the meter.
Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
