PLRF25C-1.2en Compass calibration
33
Results
The calibration result is
displayed at the end of the
procedure.
GOOD indicates a
successful calibration.
If the result is
BAD, perform
a 12 point calibration until a
GOOD is obtained. Consider
to move to an alternative
location.
Magnetic interferences can
still lead to inaccurate
measurements, even if the
calibration was successful.
For this reason the
compass accuracy should
be verified after a
successful calibration by
performing several azimuth
measurements on known
landmarks and compare the
results.
Possible causes of calibra-
tion failures:
• the device was moved
while
HOLD POS was
displayed.
• movements were
performed to fast or
jerkily.
• the location is to close to
magnetic disturber.
