5 Remarks The reference greywedge has a “0” position where the area of highest
density jumps to the area of lowest density Fig. 6-78.
The reference greywedge must not be positioned in this high-low
transition area. The adjustment will be very unstable, the wrong
position is characterised by the running bar is reacting much more
sensitive.
The proper adjustment position will allow a larger turn.
