Two wires, convenient and simple wiring, easy access to the car / battery car / motorcycle line, with reverse connection protection function, line connection reverse will not be burned, with fine-tuning function;

Function introduction: 1. Measuring range: 2.5-30v (red) 2.6-30v (yellow) 2.6-30v (green) 3.2-30v (blue) 2. It is equipped with two wires, which is convenient and simple to connect to the internal circuit of car / battery car / motorcycle; 3. It has reverse connection protection function, the reverse connection will not be burned, and it has fine adjustment function; 4. Note that the maximum input voltage should not exceed 40V, otherwise there is a risk of burning. 5. When the voltage is lower than 3.0V, the display brightness will be dimmed, but the correct measurement will not be affected. 6. When the voltage is lower than 10V, two digits will be displayed after the decimal point; When measuring the voltage above 10V, one digit will be displayed after the decimal point. It can not only meet the needs of battery users for measurement accuracy, but also meet the needs of higher voltage measurement.

The best measurement accuracy, the voltmeter will automatically move the decimal point according to the different measured voltage.
When measuring the voltage below 10V, two digits will be displayed after the decimal point;
When measuring voltage greater than 10V, one digit will be displayed after the decimal point.
It can not only meet the needs of battery users for measurement accuracy, but also meet the needs of higher voltage measurement.
This voltmeter can be used to measure the voltage of 18650 battery, mobile phone lithium battery, Ni MH battery pack and other battery packs,
It can also be used for other voltage measurement purposes
