A.3 Converting the units of measurement
The SFC−LAC calculates internally with metric units of
measurement [mm, mm/s, mm/s
2
, mm/s
3
].
The parametrizing interface (CI) works with increments
[Inc,Inc/s, Inc/s
2
, Inc/s
3
].
For representing measurements in the imperial system,
conversion is made within the FCT software [inch, inch/s,
inch/s
2
, inch/s
3
].
The distance between two index lines (= north or south pole
of the magnetic displacement encoder) is 2 mm. This equals
2048
d
(800
h
) increments. The increments are calculated by
means of interpolation.
This results in the following conversions (all figures are
decimal):
