ALIBRATION
The magnetometer of the Capsat Maritime Telephone must be calibrated after installation on
the vessel. Calibration of the magnetometer is performed automatically while slowly turning
the boat into a yaw of approximately 400 degrees. This must be performed in calm water to
keep boat roll and pitch angles as close as possible to zero. When the calibration is
completed the quality of the calibration can be read out in the handset. Calibration quality is
determined by how close role and pitch angles are kept to zero, and how constant the
turning rate is kept during the calibration procedure.
Calibration procedure
1.
Determine vertical component of magnetic field strength (the nearest port from list of
ports or from freeware software).
2.
Select magnetometer calibration mode on hand set - Menu -> Config -> Antenna ->
Compass Cal -> Start Cal
3.
Start to turn the boat at a constant rate of approximately 5 degrees per second.
4.
When the boat is turning at a constant rate, enter magnitude and sign of vertical
component of magnetic field strength on handset and the calibration measurements are
started.
5.
Note the yaw angle of the boat.
6.
Let the boat turn through 400 degrees and then terminate calibration by pressing Menu -
> Config -> Antenna -> Compass Cal -> Stop Cal . This concludes the calibration
procedure.
Interpretation of Calibration Quality Figure
Calibration quality figures can be requested by pressing Menu -> Status -> Antenna ->
Platform -> Roll.. until ‘Cal. Score’ on the handset.
The ‘Cal Score’ is a 3 digit number: the first digit is the calibration quality, the second digit is
the hard iron factor and the third digit is a count value for successful calibrations, all three
digits may vary between 0 and 9.
Left digit - quality of calibration
A calibration quality value of 9 is good and 8 is acceptable. If the calibration quality is less
than 7, the calibration procedure is rejected and must be repeated.
