2.6 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.
