Details
This command can be written to and read for resistance measurements. For current and voltage
measurements, it can only be read.
For current and voltage measurements, the upper limit is controlled by the current or voltage limit.
For resistance measurements, you can use this command when automatic range selection is enabled
to put an upper bound on the range that is used for resistance measurements.
The upper limit must be more than the lower limit.
If the lower limit is equal to the upper limit, automatic range setting is effectively disabled.
