✅ Product Description
The 0.28 inch (0.72 cm) 0-100V Three Wire DC Voltmeter – Red LED is a compact, lightweight, and highly efficient digital voltmeter, ideal for quick voltage measurements across various DC sources. With a bright red LED display and auto-adjusting decimal precision, it provides accurate and real-time readings in a minimal footprint.
Perfect for battery monitoring, DIY electronics, or embedded applications, this voltmeter supports reverse polarity protection and displays readings with up to 0.1V accuracy. It’s designed to adapt its decimal point for optimal clarity: two decimal places for voltages <10V and one decimal place for voltages >10V.
Wiring Made Simple:
-
Red Wire: Connect to the positive terminal of the power supply.
-
Black Wire: Connect to the negative terminal (common ground).
-
Yellow/White Wire: Connect to the positive side of the voltage you want to measure.
⚠️ Note: While it supports up to 30V input for display, the recommended operating range is 3.6V to 28V to prevent permanent damage due to voltage spikes or power ripples.
