9. Click to set a new calibration point.
10. Put the rudder to the hardover starboard position.
11. Read the exact rudder angle from the rudder stock scale and enter it
in the input calibration rudder angle control:
12. Click to set a new calibration point.
13. Check that all input calibration points have been stored correctly:
The calibration point index should now read “4”.
Scroll down the list of calibration points with the spin control and
verify that:
– For points 1 to 3, the rudder angles displayed are those you
entered for the hardover and midships positions. The input con-
trols will be greyed-out for the saved points.
– For each point, the number shown below the “Delete” and
“Save” button lies between 0 and 4095 and is largest for the har-
dover port and smallest for the hardover starboard value:
This number represents the 12-bit A/D conversion value of the
input voltage, at the moment when the respective calibration
point was saved.
