The wiring of this voltmeter is simple, only two wires need to be connected, the red wire is connected to the positive, and the black wire is connected to the negative. There is reverse connection protection in the meter, and the reverse connection does not burn.
This voltmeter does not require an external working power supply, it can work directly with the measured voltage, and the working voltage range is as wide as 4-30V
In order to achieve the best measurement accuracy, the voltmeter will automatically move the position of the decimal point according to the difference of the measured voltage. decimal point.
This voltmeter can be used to monitor the battery voltage of motorcycles, automobiles, etc., and grasp the battery status in time. It can also be used for other voltage measurement purposes. Featured By RoboticsBD.
