0.28inch 3.5-30V Two Wire DC Voltmeter Blue

This digital voltmeter is small and lightweight, featuring a blue LED display. It just takes a few minutes to configure the DC 3.5-30V 2 Wire Blue LED Display Digital Voltage Voltmeter Panel; all you have to do is connect the wires straight to the source you want to measure to watch the LED blink!

The black wire should be connected to the negative pole and the red wire to the positive pole. 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 can measure voltage and has a working voltage range of 3.5 to 30 volts without the requirement for an external drive. 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 30V; 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 3.5 and 30 volts.
