Note
The CLV adjusts the entire profile of the taught-in background by minus 100 mm (3.94 in),
that is, the entire background curve is moved toward the CLV by this amount (also in the
display in CLV-Setup) to compensate measurement inaccuracies. The parameterized limits
of the applicable autofocus space are not corrected. The CLV also shifts the edges of the
measured profile toward the center by 2 angular elements.
If no background has been taught in, the CLV uses the default background (2,200 mm (
86.7 in) across the entire distance profile).
