Auxiliary parameters
Additional parameters can generally be assigned once on a machine. They are then valid for
each additional measuring cycle call until modified by programming or operation.

Note
1)
All parameters with dimensions, except for those marked 1), must be programmed in the unit
of measurement of the basic system. The parameters marked 1) must be programmed in the
unit of the active system of units.
2)
_FA is always a value in mm, even when the unit system set is inches.
