Operational sequence

Position before measuring cycle call
The probe must be positioned opposite the surface to be measured.
Position after end of measuring cycle
On completion of measurement, the probe is positioned facing the measuring surface at
distance _FA.
Notice
Precise measurement is only possible with a probe calibrated under the measurement
conditions, i.e. working plane and measuring velocity are the same for both measurement
and calibration. If the probe is used in the spindle for a powered tool, the spindle orientation
must also be considered. Deviations can cause additional measuring errors.
