Measuring the surface

Position before measuring cycle call
The probe is positioned in relation to the surface to be measured in such a way that during
traversal of the specified measuring axis _MA in the direction of the setpoint _SETVAL, the
intended measuring point on the surface will be reached.
Recommended distance from surface: >_FA.
The absolute value of the positional deviation from the setpoint must not be greater than the
measuring path _FA. Otherwise, no measurement will be performed.
