This voltmeter is small in size, range DC DC0-100V, 2-wire and 3-wire products are universal, breaking the conventional voltmeter, it is the latest model design, it can work directly in 5V, 9V, 12V, 24V and other circuits, no need to stabilize the voltage. Equipped with three wires, easy to access the car/battery car/motorcycle car wiring, with reverse connection protection function, the wire connection will not burn. Used to monitor the battery voltage, timely grasp of the battery voltage status, can also be used for other products voltage measurement purposes. Note that the maximum input voltage for 2-wire use cannot exceed 30V, otherwise there is a risk of burning.
Note: 3-wire voltage range 0-100V, can also be used for 2-wire but the voltage should be within 40V.
