DESCRIPTION
This voltmeter has a huge measuring range and only need 2 wires to work! The measuring range and the input power share the same wire, so it measures directly the input power to the voltmeter. It is designed with reverse polarity protection, so no need to worry if you connect wrongly.
When the voltage is under 10V, the reading will have 2 decimal places, which means the accuracy is 0.01. When it is above 10V, the reading will be 1 decimal place, which means the accuracy is 0.1.
