This command is used to manually select the measurement range for the specifed measurement function.
The range is selected by specifying the expected reading as an aboslute value. The Model 2001 will then
go to the most sensitive range that will accommodate that expected reading. For example, if you expect
a reading of approximately 100mA, simply let the parameter (<n>) = 0.1 (or 100e-3) in order to select the
200mA range.
