This voltmeter can be used to measure the storage battery’s voltage in motorcycles and cars and also can grasp the storage battery’s status. It also can be used to measure other voltage. 30V is the voltmeter’s maximum operating limited voltage, please leave enough margin when working, to avoid voltmeter’s permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage.

Maximum input: DC30V. Note: If input voltage is higher than 30V it may permanently damage the unit.

Connections :

Red Wire: source +ve terminal.

Black Wire: Source -ve terminal.
