The course change should be made rapidly to prevent transient induced magnetism while passing the intercardinal headings
After the new heading is reached,the vessel should steam on that course for at least two minutes before the adjustment
During the course change,you should gently tap the compass to remove any error caused by friction on the pivot bearing
After steadying on the new heading,the compass card should be slewed by a magnet and allowed to oscillate freely to remove any gaussin error
