Compass
Mounting Orientation
MaxiMet should be mounted horizontally and as level as possible.
It is not possible to calibrate for changing magnetic anomalies. Thus, for greatest accuracy, keep
the MaxiMet away from sources of local magnetic distortion that will change with time; such as
electrical equipment that will be turned on and off, or ferrous bodies that will move. Make sure that
MaxiMet is not mounted close to areas that may be see large sources of local magnetic fields.
Electric motors usually generate magnetic fields that are much stronger than the earth’s field. It is
recommended that MaxiMet be moved as far away from the motors as possible.
As a guide ensure that MaxiMet is mounted at least 1 metre away from Ferrous objects to prevent
them influencing the compass reading.
Lanyard Safety Line Attachment (Gill Part 026-05335).
A 50cm stainless steel Lanyard wire (Nylon Coated) is supplied connected to MaxiMet through a
slot in the lower moulding should this feature be required to prevent it falling from height when
installed.
The Lanyard should be removed if it is not to be used.
If it is required to fit a replacement lanyard:-
Push the larger loop through the Lanyard slot and then feed through the larger loop, pull to secure.
The smaller loop end of the lanyard should be secured to the installation pole/mount etc.
The picture shows where the lanyard safety wire/line attaches to recessed post in MaxiMet.
