57 iCON grade, Calibrating the System
It’s recommended to adjust the mast mounting so that the mast is as
vertical as possible in all directions. If the mast is then extended, the
sensor mount point (A) will mainly move in the Z direction (height). If the
mast was not vertical, and it’s extended, the sensor mount point will not
only move in the Z direction but also in the X and Y direction, and a new
measurement is needed.
Left and right Blade
offset First the total blade with is measured from blade corner to blade corner.
Then the horizontal distance from the blade corner to the sensor mount
point is measured. This can be done by using a strait metal or wooden rod
and a spirit leveller.
Place the rod so that the edge of the rod is at the centre of the sensor
mount point, then use the spirit leveller to make sure that the rod is
vertical in the blade direction. Then you can measure the horizontal
distance from the rod edge to the blade corner. See Figure 2 below.
