Operational sequence

Defining the 4 points
The position of points P1 and P2 in relation to each other determines the direction of the
abscissa axis (X axis in G17) of the new coordinate system. A negative offset between P1
and P2 in the abscissa (X axis in G17) results in an additional rotation about 180°!
The position of the corner is selected with all 4 points. So for a rectangle, for example,
different corners can be selected as the zero point depending on whether measuring variant
internal or external corner is applied.
The individual points or _FA must be selected such that the contour is reached within a
Total measuring path: 2 · _FA in mm
is reached.
Otherwise, no measurement will be performed.
A minimum total measurement path of 2 · 20 mm is produced within a cycle.
