Range
The selected measurement range affects the accuracy of the measurements as well as the
maximum signal that can be measured. Note that dashed lines are displayed (i.e., --.---- µA), to
indicate that the previous measurement is not recent. This usually happens when a change occurs
such as selecting a different range.
