Details
You can assign any real number using this command. The instrument selects the closest fixed range
that is large enough to measure the entered number. For example, for current measurements, if you
expect a reading of approximately 9 mA, set the range to 9 mA to select the 10 mA range. When you
read this setting, you see the positive full-scale value of the measurement range that the instrument is
presently using.
This command is primarily intended to eliminate the time that is required by the instrument to
automatically search for a range.
When a range is fixed, any signal greater than the entered range generates an overrange condition.
When an overrange condition occurs, the front panel displays "Overflow" and the remote interface
returns
9.9e+37
