The volume of the voltmeter is the smallest in the world, and its range is DC 0-100V. The 2-wire and 3-wire products are universal. It breaks the conventional voltmeter and is the latest design. It can directly work 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.
