Seatrial and Calibration

Once a Tacktick Micronet system has been installed on the vessel and
Auto Networking has been completed it is necessary to carry out
Calibration.
Warning: It is not safe to use the displays for navigational purposes until
Calibration has been carried out correctly.
Warning: Accurate calibration is essential for successful use of the Maxi
Display's advanced functions. In particular, the calculation of Set and Drift
is sensitive to errors in the measured boat speed and the compass
heading and deviation. To ensure the maximum accuracy, calibration
must be carried out with great care.
Note: System calibration cannot be carried out using the Maxi Display,
use a Remote Display for this purpose. Refer to the Remote Display user
guide for the system calibration procedure.
To check the accuracy of your calibration, carry out the following tests:
Speed:
Run directly into and against the current; you should see the difference
between SOG and SPEED to reverse (eg SOG 6.5 and SPEED 6 running
with the current and SOG 5.5 and SPEED 6 directly into the current
would indicate a good calibration).
Compass:
In slack water with no wind, COG and HDG should match on all four
compass points (i.e. when steering a steady course North, East, South
and West).
If either SPEED or HEADING does not pass this test, refer to the Remote
Display user guide and perform the following calibrations:
Remote user guide - Speed Calibration
- perform a log calibration
Remote user guide - Compass Calibration and Alignment
- carry out a compass deviation turn
- align the heading
Remote user guide Setup - Magnetic Variation
- If your GPS is not providing Magnetic Variation data, manually set
the local Magnetic Variation.
