GM328A Mini Multifunction Transistor Tester with LCD Display

Product Overview

The GM328A Mini Multifunction Transistor Tester is a versatile tool designed for electronic enthusiasts. With its digital LCD display, rotary switch control, and automatic shutdown feature, this tester is convenient to use and energy-efficient. It can also be powered by a 9V battery or DC power (6.8-12V).

Key Features:

Digital LCD Display:** **easy readings with measured data and graphics
Rotary switch control for convenient use
Main chip is a DIP, easy for DIY or update
Automatic shutdown, shutdown current is only about 20nA
Automatic Component Identification:** **detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, and automatic identification of transistor pinout
Can be used as a square signal and PWM signal generator
Measures resistance, capacitance, and inductance
Tests NPN and PNP transistor common-emitter current amplification factor, base-emitter threshold voltage, and off collector-emitter leakage current
Supports 2 resistors measurement, shows positive and negative, on-state voltage
Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ
Automatically tests pins of a component and shows them on the display
Measures FET gate threshold voltage and gate capacitance
Measures inductance (range: 0.01mH - 20H)
Signal Generator and Frequency Meter:** **generates 1%-99% PWM signals, frequency range: 1Hz-2MHz
**Important:** **Before measuring capacitance, the capacitor must be discharged, otherwise very likely to damage the meter!!!
