Appendix D - Recalibration
Interpreting the Calibration Score
Each calibration results in a calibration score that is stored in the
system’s memory. The calibration score contains an accuracy rating, a
magnetic environment rating, and the number of calibrations
performed.
Figure D-5 Calibration Score Screen
Accuracy Rating
The accuracy rating indicates the degree of accuracy the antenna’s
internal sensor will provide based on the quality of the last calibration.
Figure D-6 lists the five possible accuracy rating levels.
Figure D-6 Accuracy Rating Levels
Magnetic Environment
The magnetic environment rating (GOOD, POOR, BAD) indicates the
environmental quality of the installation location. If the quality is
POOR or BAD, check the area around the antenna for materials that
might cause magnetic interference. Relocate the materials if possible,
or relocate the antenna to a more favorable magnetic environment.
Then restart recalibration.
Calibration Number
The calibration number indicates the number of times the antenna’s
internal sensor has been calibrated. This is primarily used to verify
that a new calibration has been accepted by the system.
