184 Chapter 6 Command Reference
To select autorange, 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.
•
The following tables show the max._input parameters and the ranges they select
for each measurement function.
