This voltmeter has a volume of 0.36 inches , a range of DC 0-100V , and is common to 2 and 3 wire products. It breaks the conventional voltmeter and is a new design. It can work directly in 5V , 9V , 12V , 24V and other circuits without the need for voltage regulation. Equipped with three wires , it is convenient to access the lines in the car / battery car / motorcycle. It has the reverse connection protection function, and the connection will not burn. It is used to monitor the battery voltage, to grasp the battery voltage status in time, and can also be used for voltage measurement of other products. Note that the high input voltage of the 2- wire cannot exceed 30V, otherwise there is a risk of burning .
Note: The voltage range of the 3-wire is 0-100V, and it can also be used as the 2-wire, but the voltage should be within 30V
