12. The span of the rotator has now been calibrated. To calibrate the absolute azimuth, it is necessary to
enter two points as far apart as possible but at least 30 degrees from the limits on each end of the
rotation.
13. Start with the rotator at the CW limit and turn the rotator counter clockwise (CCW), at least 30 deg from
the clockwise limit. Enter the azimuth of the rotator as accurately as possible into the entry field.
14. Turn rotator at least 90 degrees further counter clockwise (CCW), but not within 30 degrees of the
counter clockwise limit. Enter the angle through which you turned rotator counter clock wise from
previous calibration point as accurately as possible.
If you have multi turn rotator and you turned the rotator more than 360 deg, you must enter cumulative
angle value. For example, if you turned rotator exactly one and half turns counter clockwise, enter 540
deg (180+360).
15. Click Finish. The new calibration values are automatically stored to Station Master.
Rotator Quick Calibration
Due to their nature, PULSE sensor rotators need occasional recalibration. In these cases it is only necessary
reset the current heading.
IMPORTANT: Quick Recalibration cannot be used before performing a full calibration and is available only for
PULSE sensor rotators.
NOTE: The previously defined parameters and delays are used during Quick calibration.
1. Click Adjust button.
2. Set antenna to a known azimuth.
3. Enter value of this azimuth to the entry field.
4. Click OK. New calibration values are automatically stored into Station Master.
