This Red Green Blue DC Voltage Meter with DC4.5/4.7/5V-30V range.
It is easy to read, install and use
And it is self-powered version and supports Reverse polarity protection.
When the voltage is under 10V, there will 2 readings after decimal point,
which mean the accuracy is 0.01 when it is under 10V;
when it is above 10v, the accuracy is 0.1
