•
Due to the magnetic influence from metal parts on a standard EMM 2.0 it is recommended to add an external
compass to the sensor or to the system.
•
NOTE! After external compass has been mounted avoid mounting magnetic objects in the vicinity of the
compass.
10.4.2
Recommended sensor location
•
It is difficult to avoid magnetic distortion areas on the lower parts of an EMM 2.0. It is therefore recommended to
add an external compass to the system.
•
The best location for mounting the sensor is:
1.
As close to the center of the buoy as possible.
2.
As close to the waterline as possible.
-
For buoys with central canister it is recommended to mount the sensor inside the canister.
-
For buoys without central canister the sensor can be fixed to the surface of the buoy flotation.
