List of operating parameters
P1 Unit of measurement 1)
Display in millimeters mm
Display in inches inch
P11 Activate scaling factor 1)
Scaling factor active SCALING ON
Not active SCALING OFF
P12.1 to P12.3 Enter scaling factor 1)
Enter a scaling factor separately for each axis:
Entry value > 1: workpiece will “grow”
Entry value = 1: workpiece will remain the same size
Entry value < 1: workpiece will “shrink”

Factory setting: 0
Example Displayed length Ld = 620.000 mm
Actual length (as determined for example with
the VM 101 from HEIDENHAIN)
La = 619.876 mm
Difference

L = La – Ld = –124 µm
Compensation factor k:
