Operational sequence

Position before measuring cycle call
The probe must be positioned opposite the positive measuring point.
Position after end of measuring cycle
After the end of measurement, the probe is facing the negative measuring point 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.
