2 wire
DC4.5-30V
This Red Voltage Meter withDC4.5-30Vrange. 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
