5. Select the device that the transducer you are calibrating is connected to.
A list of available transducer data is displayed.
6. (1) Select Speed .
Important:
(1)Step only applicable to iTC-5.
7. Select Speed Calibration .
8. Select New cal using SOG .
You will need to add calibration points at a range of speeds spanning the full speed range of the
vessel. Conventional transducers can have up to 5 calibration points and smart transducers can
have up to 8. Ideally the calibration points should be taken at regular increments throughout the
speed range with the last calibration point being close to the vessel’s top speed.
With the Speed Transducer connected to a Speed Pod the 5 calibration points are fixed in
sequence at 2, 4, 8, 16 and 32 knots. When adding calibration points during the Speed Run
Calibration ensure vessel speed is as close to the fixed calibration point speeds as possible, as
the calibration factor applied will be the difference between the actual vessel speed and the
fixed calibration point speed.
9. Select Start .
10. Ensure the vessel’s speed is steady at your first calibration point speed and select Add .
11. Repeat step 10 for all remaining calibration points, ensuring that the calibration points are equally
spaced throughout your vessel’s speed range from stationary to top speed.
Once all calibration points have been successfully added the Calibration complete message is
displayed.
12. Select OK .
Calibration table
By default speed transducers include a default set of calibration points which are overwritten during
the normal speed calibration process. The calibration points are stored in the calibration table. The
calibration table can be accessed from the Advanced menu.
From the
Advanced menu you can:
• View the existing calibration table
• Adjust the existing calibration points (Add, Edit or Delete calibration points)
• Enter a new calibration table
• Check Log Speed against SOG
• Reset the calibration table to factory defaults
