Product description:

1. The wiring of this voltmeter is simple, only need to connect two wires, the red wire is connected to the positive, the black wire is connected to the negative, the meter has reverse connection protection, and the reverse connection will not burn.

2. This voltmeter does not require an external working power supply, and can work directly with the measured voltage, with a wide working voltage range of 4.5-30V.

3. 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. When measuring voltage below 10V

When measuring voltage above 10V, it will display two digits after the decimal point; when measuring voltages above 10V, it will display one digit after the decimal point.



4. 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.

Note the list:

1. 30V is for the meter voltmeter. The high limit operating voltage, please pay attention to leave enough margin for the meter when using it to avoid motor sparks and power ripples

Or other excessively high sudden voltages can damage the voltmeter for a long time.



2. This voltmeter has not been treated with moisture-proof, water-proof, shock-proof and oil-proof treatment, please pay attention when using it, or dispose of it yourself.
