Calibrating wind

Calibration of wind transducers is important to ensure accurate data is displayed.

Note

The following details apply to legacy Long arm and Short arm wind vane transducers and the Rotavecta wind transducer.

Prerequisites:

You will need to be underway, with sufficient space to turn in a large slow circle unhindered.
Conditions should be calm (i.e. a slight sea) and a steady breeze. Try to ensure the vessel is not rolling or pitching too much.

The display will search for and show a list of connected devices. (i.e. iTC-5, DST or transducer pod)
Select the device that the transducer you are calibrating is connected to.
A list of available transducer data is displayed.
⁽¹⁾Select Wind.
This step is only applicable when calibrating a wind transducer connected via an iTC-5.
Select Calibrate Wind Xdcr.
Keep the vessel speed below 2 kts and observing the screen, start to turn the vessel in a circle, then select Start.
Continue turning the vessel in circles until ‘Complete’ is displayed onscreen.
If your rate of turn is too fast during calibration, a ‘Slow down’ message is displayed. If this happens, reduce your rate of turn, this can be achieved by slowing down and / or steering in a wider circle.
Select Continue.
If required, use the UP and DOWN buttons to manually adjust the offset.
Press SELECT to complete the calibration process and save the settings.

If required, you can manually adjust each part of the calibration steps by selecting the relevant options from the Wind menu.
