DIY GM328 Transistor Tester Frequency Diode Cap LCR ESR Volt Freq Meter PWM Square Wave Signal Generator

Features:

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.

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.

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.


Description:

Multi-functional transistor tester for automatic detection of NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout. Also can be used as square signal and PWM signal generator.


Notice:

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