GM328 Transistor Tester Frequency Tester PWM Square Wave LCR Meter Voltmeter Full Color Screen Graphics

GM328 LCD Meter with Display

This versatile transistor tester automatically detects NPN and PNP transistors, as well as FETs, diodes, dual diodes, thyristors, and SCRs. GM328 LCD Meter with Display also identifies the pinout of the transistor and can generate square and PWM signals.

Included in this product are a variety of impressive characteristics.

• The LCD display conveniently shows both numerical and graphical data.
• Efficient operation is made effortless with the inclusion of a rotary switch control.
• The primary chip, known as the DIP, is ideal for individuals with a passion for electronics as it allows for easy DIY projects and updating of the main chip.
• GM328 LCD Meter with Display requires a 9V battery (not included) or a DC power source with an input range of 6.8-12V.
• The current for automatic shutdown is approximately 20nA.
• GM328 LCD Meter with Display can automatically identify various electronic components such as NPN and PNP transistors, FETs, diodes, dual diodes, thyristors, and SCRs. It also has the capability to detect the pinout of transistors with ease.
• Measure the gain, threshold voltage, and leakage current of both NPN and PNP transistors in common-emitter configuration.
• The device can support 2 resistors for measurement and display their positive and negative on-state voltage.
• The maximum resolution for resistance measurement is 0.01Ω, with a capability of measuring up to 50MΩ.
• Perform automatic testing on the pins of a component and display the results.
• Take measurements of the FET gate threshold voltage and capacitance.
• When measuring inductance for a 2100Ω resistor, the range should be set from 0.01mH to 20H.
• This versatile device functions as both a signal generator and frequency meter. With a frequency range of 1Hz-2MHz, it is capable of producing PWM (pulse width modulation) signals ranging from 1% to 99%.

Please take note that…

Prior to measuring the capacitance, it is necessary to discharge the capacitor in order to prevent potential damage to the meter.
