Source-measure operations are performed using either 2-wire local sense connections or 4-wire remote sense
connections. Writing to this attribute selects the sense mode.
The smuX.SENSE_CALA mode is only used for calibration and may only be selected when calibration is enabled.
The sense mode can be changed between local and remote while the output is on.
The calibration sense mode cannot be selected while the output is on.
Resetting the instrument selects the local sense mode.
