The voltmeter has a volume of 0.36 inch, a range of DC dc0-100v, which is common for 2-wire and 3-wire products. It breaks the conventional voltmeter. It is the latest design, which can be directly used in 5V, 9V, 12V, 24V and other circuits without voltage stabilization. Equipped with three wires, it is convenient to connect to the lines inside the car / battery car / motorcycle, with reverse connection protection function, and the reverse connection will not burn. It is used to monitor the battery voltage and master the battery voltage status in time. It can also be used to measure the voltage of other products. Note that the maximum input voltage of 2-wire should not exceed 30V, otherwise there is a risk of burnout.
Note: the voltage range of three wires is 0-100V. It can also be used as two wires, but the voltage should be within 30V
