19.6 Deselecting the Reference Run for Axes
For axis examinations it is possible to deselect the referencing in MP 1340.x .
8 Enter value 0 (= no evaluation of the reference mark) for the corresponding axis or for all axes.
Note
In MP1340.x the sequence for the reference mark run is listed.
With following entries, i.e.:
 MP1340.0 : 3
 MP1340.1 : 2
 MP1340.2 : 1
... first the 3rd axis is referenced (e.g., Z axis), then the 2nd axis (e.g., Y axis) and
subsequently the 1st axis (e.g., X axis).
If you now want to deselect the X axis, you must enter MP1340.2 = 0!
However, the reference run is normally deselected for all axes.
