P41.1 L.COMP. Linear error compensation X1
– 99 999.9 < P41 < + 99 999.9 [µm/m]
Default setting: 0
Example: Find input value for P41
Displayed measuring length ............. L
a
= 620.000 mm
Actual length (measured, e.g.
with the VM 101 comparator
system from HEIDENHAIN) .............. L
t
= 619.877 mm
Length difference .............................
∆
L = L
t
– L
a
= – 123 µm
Compensation factor k (= P41):
k =
∆
L / L
a
= – 123 µm / 0.62 m ........ k = – 198.4 [µm/m]
