Variable measuring speed
The measuring velocity can be freely selected by means of _VMS. The maximum measuring
velocity must be selected to ensure safe deceleration within the probe deflecting path. ->

Weighting factor for mean value calculation
The weighting factor k can be applied to allow different weighting to be given to an individual
measurement.
A new measurement result thus has only a limited effect on the new tool offset as a function
of k.
Zero offset area
This tolerance range (lower limit _TZL) corresponds to the amount of maximum accidental
dimensional deviations. If the absolute value of the actual/set difference is less than the zero
offset range, the offset is not applied.
ZO determination
In the result of a measurement, the actual-setpoint value difference is stored in the data set
of any settable zero offset.
