Description
The voltmeter is a compact mini DC 0-100V voltage measuring device to measure 2 line and 3 wire products, general use, break through digital dc volt meter, is the latest design, can work directly in 5V, 9V, 12V, 24V and other circuits, without voltage regulation. Equipped with three wiring, easy access to the car / storage battery car / motorcycle inside line, with reverse connection protection function, line connection will not burn. Used to monitor the battery voltage, timely grasp the state of battery voltage, can also be used for other products voltage measurement purposes.
Wiring Diagram:
Please check and follow the circuit diagram before connecting this digital dc volt meter.
Features of DC Volt Meter:
- Small in size and light in weight, quite easy and convenient to carry out.
