0.7 cm (0.28 inch) 0-100V Three Wire DC Voltmeter Red
This is a tiny and compact digital voltmeter with a red LED Display. The 0.7 cm (0.28″) 0-100V Three Wire DC Voltmeter Red Panel requires only a few minutes of configuration and is as simple as directly connecting wires to the source you want to measure and seeing the LED blink. 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. 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 won’t be a boom because it features reverse polarity protection.To reach the best measurement accuracy, this voltmeter will automatically move the decimal point’s position according to the different measuring voltages.
Wire configuration:
- 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
