Do not need power supply, can measure 2.5-30V directly.
If the input voltage is below 3.5V, the display brightness dims.
If the input voltage is below 2.7V,measuring inaccurate or no display.
when measure 10V below, accurate to 0.01V,display x.xx.
when measure 10V or more, accurate to 0.1V,display xx.x.
