Voltmeter Module Three Wire 0-100V DC 0.36″ Red

This digital Voltmeter comes with 3 wires. Only two wires are required to connect this device to the target circuit for voltages up to 30V, and the same DC voltage utilised by the target circuit is used to power this voltmeter. For applications requiring measurements of more than 30V, three-wires and an additional power supply are used.

The red wire is to connect to the positive pole, the black wire is to connect to the negative pole and the yellow/white wire is to connect to the positive pole of that source or another source across which we meant to measure the voltage, refer image. While measuring the supply voltage of another source make sure that the negative pole is joined common. No need to worry even if there is any connection mismatch of the wires, the electric circuit wonÕt be a boom because it features reverse polarity protection.
