How It Works
The voltmeter connects directly across the DC power source using its two wires. It continuously measures the input voltage and displays the measured value on the built-in LED display in real time. This makes it ideal for monitoring batteries, power supplies, and other DC-powered systems without requiring additional controllers or programming.
