2-Wire DC Voltmeter With 0.56-Inch LED Digital Voltmeter For DC4.5V-30.0V Reverse Connection ProtectionItem NO.: 2wire0.56

2-Wire DC Voltmeter With 0.56-Inch

Product Introduction:

1. 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 protection inside the meter, and reverse connection does not burn.

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

3. To achieve optimal measurement accuracy, this voltmeter will automatically move the decimal point position according to the different measured voltages. When measuring voltage below 10V, display two decimal places after the decimal point; When measuring voltage above 10V, display one decimal place after the decimal point.

4. This voltmeter can be used for monitoring battery voltage on motorcycles, cars, and other vehicles to timely grasp the battery status. It can also be used for other voltage measurement purposes.

Precautions:

1. 30V is the maximum voltage for a voltmeter. When using it, please leave enough margin to avoid long-term damage to the voltmeter due to motor sparks, power ripple, or other high and sudden voltage changes.

2. This voltmeter has not undergone moisture-proof, waterproof, shockproof, or oil-resistant treatment. Please be careful when using it or dispose of it yourself.
