2. Highlight and select each calibration speed to display the
calibration options menu, which will show the following options:
• Add using SOG — To add a speed value to the list of
calibration speeds.
• Add — To add a speed value to the list of calibration speeds
without using SOG.
• Delete point — To remove a speed value from the list of
calibration speeds.
• Edit — To edit a speed value in the list of calibration speeds.
• Reset — To reset the calibration to its factory default.
3. Add using SOG .
When adding a point you will see the following:
• Current vessel speed over ground (SOG).
• DST Frequency (provided for information only).
i. Adjust your vessel speed until the SOG is at the desired
calibration speed.
ii. Press OK to confirm the calibration speed entry.
iii. Repeat this for each calibration speed appropriate for your
vessel.
4. Add
i. Use the UP and DOWN buttons to set the paddlewheel
frequency at which to add a calibration point.
ii. Press NEXT .
iii. Use the UP and DOWN buttons to set the correct vessel
speed at the paddlewheel frequency chosen.
iv. Press OK .
5. Delete point
i. Press YES to confirm and delete the selected speed.
ii. Press NO to ignore any changes and return to the list of
calibration speeds.
6. Edit .
i. Use the UP and DOWN buttons to adjust the current speed
value.
ii. Press SELECT to confirm change and return to the list of
calibration speeds.
7. Reset
i. In order to reset the DST to factory default settings press
the
YES key.
ii. To return to the previous screen without resetting press the
NO .
Note: Resetting to factory defaults will remove any saved custom
settings.
8. When you have completed the speed calibration, press BACK to
return the relevant transducer page
Calibrating speed manually
You only need to carry out a manual speed calibration if SOG data
is not available. If you have successfully calibrated your system
using SOG data, ignore this manual procedure.
1. From the Transducers found page highlight and select the
relevant conventional or smart transducer.
2. Highlight and select Speed Calibration .
You will see various calibration speeds provided by the system
(up to 5 for conventional transducers and up to 8 for smart
transducers).
3. You will need to calibrate each calibration speed, starting with
the lowest, highlight the calibration speed and press SELECT .
4. In calm conditions with zero tide and zero current, run your
vessel at a steady speed, approximately that of the selected
calibration speed, over a measured distance, making a note of:
• The current speed value.
• The time it takes to cover the measured distance.
