4.7 EV-1 heading sensor
You can connect an EV-1 heading sensor to your display, this will ensure that
accurate heading data is available, regardless of vessel movement.
The EV-1 heading sensor will automatically calibrate (linearize) itself while the
following conditions are met:
• vessel speed is between 3 to 15 knots, and
• at least a 270° turn has been made.
Note:
The time it takes for automatic calibration can be reduced by completing a
full 360° turn at between 3 to 15 knots.
After the initial calibration has been completed a notification will be displayed
and a Max deviation value will be reported in the
[EVO COMPASS]
section
of the
[This display]
menu. If dashes are displayed then the calibration has
not been successful.
If the Maximum deviation is 45° or greater, it is recommended that either the
EV-1 is relocated, in a location with less magnetic interference, or that any
devices causing magnetic interference are moved farther away from the EV-1.
Manually adjusting an EV-1 heading sensor
If there is a difference between Heading and the reported COG (Course Over
Ground), which is not attributable to tide and wind conditions, then you can
adjust the EV-1 heading sensor’s settings to compensate.
The EV-1 settings can be accessed from the
[This display]
menu:
[Homescreen > Settings > This display > EVO set-up]
.
1. If the difference is within plus or minus 10°, then select the
[Compass
offset]
field and adjust until COG and heading values are the same, or
2. If the difference is greater than plus or minus 10° you can align your
heading sensor to the COG, reported by you GPS/GNSS, by selecting
[Align to GPS]
and following the onscreen instructions.
Restarting calibration
If you experience problems with your heading data or have had to relocate
the EV-1 sensor then you can restart the automatic calibration.
From the this display menu:
1. Select
