Determine entry value for P41
Example: Displayed measuring length L a = 620.000 mm
Actual length (determined with, for example, the VM 101
comparator system from HEIDENHAIN) L t = 619.876 mm
Length difference ∆L = L t – L a = –124 µm
Compensation factor k:
k = ∆L / L a = –124 µm / 0.62 m = –200 [µm/m]
