Garmin STEADYCAST HEADING SENSOR User Manual

chartplotter, you must perform basic
calibration instead of menu-based calibration
(page 4).
Performing Menu-Based Calibration
Before you can perform menu-based
calibration, you must connect the sensor to
the same NMEA 2000 network as a
compatible Garmin chartplotter.
If the sensor has not been calibrated
successfully , a message appears each time
you turn on a compatible Garmin chartplotter .
1 From the sensor calibration screen, ·
select Compass Cal ..
TIP: You can open the calibration page at
any time by selecting the device from
Menu > Settings > Communications >
NMEA 2000 Devices.
2 Select Begin.
3 Follow the on-screen instructions until the
compass calibration is complete, taking
care to keep the boat as steady and level
as possible .
The boat should not list during
calibration.
If possible, you can turn the vessel in
pl ace by engag i ng two engines in
opposite directions.
When the compass calibration is
complete , a value appears near the
Compass Cal. setting. A value near 100
indicates the sensor was installed in a
perfect magnetic environment and
calibrated correctly. If the heading
performance is unacceptable, and the
value is closer to 0 than it is to 100, you
might need to relocate the sensor and
calibrate the compass again .
4 Select Auto Heading Alignment.
NOTE: Auto Heading Alignment is
available only if there is a GPS source
connected to the NMEA 2000 network . If
you do not have a GPS source
connected , you must perform the Fine
Heading Alignment instead (page 4) .
5 Select Begin .
6 Follow the on-screen instructions until the
alignment is complete.
Adjusting the Fine Heading Alignment
If you do not have a GPS source connected
to the NMEA 2000 network, Auto Heading
Alignment is not available as part of menu-
based calibration, and you must adjust the
Fine Heading Alignment instead .
You can adjust the Fine Heading Alignment
in conjunction with Auto Heading Alignment
to fine-tune the heading output ( optional) .
1 From the sensor calibration screen ,
select Fine Heading Alignment.
2 Using a landmark or a known good
compass, determine the heading of your
boat.
3 Adjust the heading until it matches your
measurement.
4 Select Done .
Performing Basic Calibration
If you connect the sensor to a NMEA 2000
network without a compatible Garmin
chartplotter , you must perform basic
calibration instead of menu-based
calibration .
You must be able to view heading data from
the sensor on a connected chartplotter or
marine display before you can perform basic
calibration . If you cannot view heading data
on your connected display, check the NMEA
2000 network and power connections.
All other sources of heading data that are not
based on GPS must be removed from the
NMEA 2000 network while performing basic
calibration.
When performing basic calibration , you first
calibrate the compass and then align the
heading in one continuous procedure. If you
insta ll ed the sensor with the cable pointing
toward the bow , parallel to the keel, it may
not be necessary to align the heading.
NOTE : If you choose to align the heading ,
you must connect a GPS source to the
NMEA 2000 network . The boat must be able
to reach a cruising speed of at least 6.4 km/h
(4 mph) to perform the heading alignment.
1 Drive the boat to a locat i on with calm ,
open water.
2 Set the display to view heading data from
the connected sensor .
3 Disconnect the sensor from the NMEA
2000 network or turn off the power to the
NMEA 2000 network.
4 Wait while the boat becomes level and
stationary.
5 Turn on power to the sensor , and wait
until the heading data appears on the
di splay G) .
6 Within three minutes , complete two full ,
slow, tight circles @, taking care to keep
the boa t as steady and level as possible .
The boat should not list during
calibration .
If possible , you can turn the vessel in
place by e ngaging two engines in
opposite directions .
