0.28inch 0-100V Three Wire DC Voltmeter Red
Introducing the 0.28-inch 0-100V Three-Wire DC Voltmeter Red Panel, a compact and efficient tool for voltage measurement. Setting up this voltmeter is a breeze – simply connect the red wire to the positive pole, the black wire to the negative pole, and the yellow/white wire to the positive pole of the source you wish to measure. When measuring voltage across another source, ensure the negative poles are connected in common. Rest assured, its built-in reverse polarity protection safeguards against any wiring mismatches.
This voltmeter operates with remarkable simplicity, requiring only a few minutes for configuration. It automatically adjusts the decimal point’s position for optimal accuracy based on the measured voltage. For voltages below 10V, it displays two decimal places, while for voltages above 10V, it shows one decimal place.
With its versatile range of 0V to 100V, this voltmeter is suitable for various applications, from checking storage battery voltage in motorcycles and cars to measuring other voltage sources. However, it’s important to note that the maximum operating voltage is 30V, so exercise caution and leave enough margin during operation to prevent any potential damage from electrical spikes or fluctuations.
Featuring a bright and clear LED display, this voltmeter ensures easy readability even in different lighting conditions. Whether you’re tackling automotive diagnostics or engaging in DIY projects, this tool is indispensable for accurately measuring DC voltages within the range of 0V to 100V.
Connections :
Red Wire: Positive of the Power supply
Black Wire: Negative of the Power supply and also used as the negative of the measurement voltage source
Yellow/White/Blue: Positive of the measurement voltage source
CASE 1: If you have only one power source to give Power as well as to measure the voltage

CASE 2: If you have to measure the voltage of another source then

Note: The display weight and Dimensions may have ±2% error.
