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.
