Accuracy (ACC)
The ACC data indicates the sensor's degree of accuracy. Table 3-3
lists the five possible accuracy levels.
Magnetic Environment (MAGENV)
The MAGENV score (GOOD, OK, POOR, BAD) indicates the
quality of the installation location. If the quality is POOR or BAD,
the antenna may need to be moved to a more favorable magnetic
environment, or the source of magnetic interference needs to be
relocated.
Calibration Update Number (CAL #)
The CAL # indicates the number of times the sensor has
calibrated itself. It is used primarily to verify whether a new
calibration has been accepted by the system.
