Use the menu system to enter the calibration factor in menu C1.1. Note that the correlation shall be
expressed in percentage.
4.2.3 Speed Depending Calibration (Multiple Point Calibration)
This type of calibration is meant for vessels needing varying speed compensation in the whole speed
register. Up to ten different speeds can be calibrated for, spread to speeds both ahead and astern.
Speeds between the calibration points are interpolated automatically, except the area nearest zero,
which uses its nearest calibration factor down (up) to speed zero.
The Multiple Point Calibration can be ENABLED and DISABLED in menu C3. Store the setting by
pressing the ENTER button.
Make the calibration runs and calculations as described above for Single Point Calibration, but now
repeat the procedure for each speed desired.
Before the calibration runs, make sure
x that correct TRU-calibration factor is set (see above)
x that the chosen draught condition (e.g. BALLAST 1) is set to 0% (Menus C1 and C2)
x that the Multi Point Calibration is DISABLED (Menu C3)
Due to the interpolation between the compensation factors the Multi Point Calibration must be
DISABLED during all calibration runs, also when making a later run for an extra calibration point.
