0.28inch 0-100V Three Wire DC Voltmeter Green

This digital voltmeter is small and lightweight, featuring a green LED display. It just takes a few minutes to configure the 0.28-inch 0-100V Three Wire DC Voltmeter Green Panel; all you have to do is connect the wires straight to the source you want to measure and see the LED blink!

The yellow/white wire should be connected to the positive pole of that source or to another source that we intended to measure the voltage across. The red wire should be connected to the positive pole, the black wire to the negative pole. Make sure the negative pole is connected to the common when monitoring the supply voltage from another source. Because the electric circuit has reverse polarity protection, there’s no need to worry even if there is a mismatch in the wire connections.

This voltmeter will automatically adjust the decimal point’s location based on the various measuring voltages in order to achieve the highest measurement accuracy. It will display the voltage reading two places after the decimal point if it is less than 10V. It will show one place after the decimal point if the voltage is higher than 10V.

This voltmeter can be used to determine the voltage and condition of the storage battery in vehicles and motorbikes. Other voltages can also be measured using it. The maximum operational voltage of the voltmeter is 100V; thus, when operating, please allow sufficient margin to prevent irreversible damage to the voltmeter from an electrical spark, ripples in the power supply, or other very high abrupt voltage changes.

An very bright and respectable LED display is prepared to test DC voltages between 0 and 100 volts.

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.
