Best Answer

When a meter has several scales, it also has a switch that allows you to select

the most convenient scale for each individual measurement, so only one scale is

used for one measurement. That gives you the ability to make the most accurate

measurements over a wide range of voltage or current, almost as if you had two

or three different meters.
