Lgroup <Name; Ohms Ranges; [:Upper] <N - Keithley 6517B Reference Manual

Section 14: SCPI command reference
:LGRoup <name>
This command selects the coloumbs autorange limit.
Usage
[:SENSe[1]]:CHARge:RANGe:AUTO:LGRoup <name>
:LGRoup?
<name>
Details
This command is used to set the autorange limit for the coulombs function. With HIGH selected, the instrument
only autoranges between the two high coulombs ranges (200 nC and 2 µC). With LOW selected, the instrument
only autoranges between the two low coulomb ranges (2 nC and 20 nC).

[:UPPer] <n>
This command is used to set the measurement range for Auto and Manual V-source Ohms.

Details
These commands are used to manually select the measurement range for the ohms function. The range is
selected by specifying the expected reading as an absolute value. The Model 6517B then goes to the most
sensitive range that accommodates that expected reading. For example, if you expect a reading of approximately
100 M, simply let the parameter (<n>) = 100e6 to select the 200 M range.
