Preparation for measuring operation
Prerequisites for a precise measuring run
The following preparations have to be made to ensure maximum accu-
racy when measuring with the CMM.
The CMM must be adapted to room temperature prior to the mea-
suring run. Recommendation: The CMM should always remain on.
1 Switch the CMM on at least 30 minutes before starting the measur-
ing run.
The heat of the hand may influence the properties of probe holder
and probe. The components should therefore be installed before
starting the measurement.
2 Mount the probe to the CMM at least 15 minutes before starting the
measuring run.
3 Always carry out a reference measurement after the reference point
travel and qualify each stylus used for measurement.
4 Carry out temperature compensation.

system. It is located in the upper left corner of the measuring volume.
The home position must be determined by a homing run
prior to the
measuring run.
