According to EN999 and EN294:
The height of the protective field "H" above the reference plane and the reso-
lution "d" of the MS2800 system have the following relationship:
S =
(K x T) + C
For K and T please refer to the previous chapter
C =
8 x (d - 14)
d = resolution of the MS2800 system
S =
(2000 mm x T) + 8 x (d - 14)
