【Ready Stock】 for DC 4.5V-30V Digital Voltmeter 0.56" LED 2-Wires Voltage Volt Meter Panel Gau

-This voltmeter's wiring is simple,it only need to connect two wires,the red wire is to connected to positive pole,the black wire is to connected to negative pole.

-There is for protection when the wires aren'for t correctly connected,the electric circuit won'for t be bumed.

-This voltmeter doesn'for t need external drive working power,it can work with measuring voltage,the working voltage's range is 4.5-30V.

-To reach the best measurement accuracy,this voltmeter will automatically move the decimal point's position according to the different measuring voltage. When it measures the voltage below 10V,it will display two places after decimal point. When it measures the voltage above 10V,it will display one place after decimal point.

-This voltmeter can be used to measure the storage battery's voltage in motorcycles and for cars and also can grasp the storage battery's status. It also can be used to measure other voltage.
