PS 000x March 2015 Gill Instruments Ltd 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 re
