GM328A Mini Multifunction Transistor Tester with LCD Display

GM328A Mini Multifunction Transistor Tester with LCD Display

Features:

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

• Rotary switch control is a key measurement for convenient use

• The 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, and automatic identification of the transistor pinout

• It also can be used as a square signal and PWM signal generator

• It can be used to measure resistance, capacitance and inductance

• 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 them 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 a signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM(pulse width modulation) signals

• Before measuring capacitance, the capacitor must be discharged, otherwise very likely to damage the meter!!!
