A.3 Converting the units of measurement
The CI interface works with increments
[Inc, Inc/s, Inc/s
2 , Inc/s 3 ].
DNCE−...−LAS The distance between two index lines (= north or south pole
of the magnetic displacement encoder) is
5 mm.
The resolution of the measurement system is 11 bits, which is
the same as 2048
d
(800
h
) increments. The increments are
calculated by means of interpolation. This results in the
following conversions (all figures are decimal):
[Inc] > [mm]
mm
+ xĄInc
2048ĄInc
5Ąmm
[mm] > [Inc]
Inc
+ xĄmm
5Ąmm
