A.3 Converting the units of measurement
The CI interface works with increments [Inc, Inc/s, Inc/s

,
Inc/s
3
].
DNCE−...−LAS The distance between two index lines (= north or south pole
of the magnetic displacement encoder) is 5 mm. The resol
ution of the me
asurement system is 11 bits, which is the
same as 2048
d
(800
h
) increments. The increments are calcu
lated by means of interpolation. This results in the following
conversions (all figures are decimal):
