The voltmeter is a compact mini DC 0-100V voltage measuring device to measure 2 line and 3 wire products, general use, break through voltage 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.
Note that the 2 line using the highest input voltage shall not exceed 30V, otherwise there is danger of burnout.
Note: three line voltage range 0-100V, can also be used for second-line, but the voltage should be within 40V
