Description 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.
Programming example 10 OUTPUT 716; “:curr:ac:rang 125e-6; rang?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Specifies the expected reading to be 125µA AC, and then queries the selected measurement
range.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the currently selected measurement range (0.0002).
