Using the MIN, MAX, and DEF Parameters
For many commands, you can substitute "MIN" or "MAX" in place of a
parameter. In some cases you may also substitute "DEF". For example,
consider the following command:
VOLTage:DC:RANGe {<range>|MIN|MAX|DEF}
Instead of selecting a specific value for the <range> parameter, you can
substitute MIN to set the range to its minimum value, MAX to set the range to
its maximum value, or DEF to set the range to its default value.
