Product introduction:
1. This voltmeter wiring is simple, it only needs to take two lines, the red line is positive, the black line is negative, the table has the anti-protection, the reverse does not burn.
2. The voltmeter does not need to be connected to the work power, it can work directly with the measuring voltage, the working voltage range is 4.5-30V.
3. For optimal measuring accuracy, this voltmeter will automatically move the decimal point according to the different measurement voltage. When measuring the voltage below 10V, the decimal points are shown two; After measuring the voltage of 10V, the decimal will show one.
4. This voltmeter can be used to monitor the voltage of electric bottle, such as motorcycle, car, etc. It can also be used for other voltage measurement purposes.

Note:
1. 30V is the highest limit of table voltmeter using voltage, please pay attention to when using leave enough margin for table, to avoid electrical spark, the power supply ripple or other mutations cause permanent damage to the voltmeter too high voltage.
2. This voltmeter does not make moistureproof, waterproof, shockproof, anti-pollution treatment, please pay attention when using, or self-handle.
