RANGE
The RANGE command allows you to select a measurement range or the
autorange mode.
Syntax
RANGE [max._input][,%_resolution]
max._input
The max._input parameter selects a fixed range or the autorange mode. To select
a fixed range, you specify the max._input as the absolute value (no negative
numbers) of the maximum expected amplitude of the input signal. The multimeter
then selects the correct range. To select the autorange mode, specify AUTO for
max._input or default the parameter. In the autorange mode, the multimeter
samples the input signal before each reading and selects the appropriate range.
