The voltmeter is small, only 0.36 inches, range DC DC0-100V, 2 and 3-wire generic products, to break the routine voltmeter, is the latest design, can work directly on 5V, 9V, 12V, 24V and other circuits, without regulation. With three wiring, easy access to car / battery car / motorcycle car line, with reverse polarity protection function, line reversed not burn. Used to monitor battery voltage, grasp the battery voltage state, it can also be used for other products voltage measurement applications.
Feature:
1. product stability, high measurement accuracy
2. Overall standard size, easy installation
3. Power supply protection circuit using a polar
NOTE: Three-line voltage range 0-100V, but also for the use of second-line voltage is within 30V, otherwise there is a danger of burning.
