North Seeking Status
The north seeking status view guides the user through the north seeking initialisation
procedure and provides feedback on the progress. It is not necessary to use this
dialogue to perform the north seeking initialisation, however it can be very helpful for
users getting accustomed to the process. The error value provided gives an
approximation of the bias convergence accuracy. A good initialisation should yield an
error of less than 10%. Each quadrant represents a 90 degree segment about the Z
axis in which data must be collected and the unit starts at zero degrees in quadrant 1
when powered on, see Illustration 46.
