Step 12. Rotate VG in the next position and repeat Step 11 as many
times as you need. Azimuth value for each new position can be entered in
the “Yaw” field directly or as relative azimuth in the right field. It is
measured by means of object sight unit or separate device (like theodolite).
Azimuth of these relative position can be set in degrees or in mils
depending on chosen item in drop-down list «(deg) / (mils)». Relative
azimuth in degrees is considered to be positive in case of clockwise
rotation from reference to calibration point and negative in case of counterclockwise rotation. Relative azimuth in mils is positive in case of counterclockwise rotation from reference to calibration point and negative in case
of clockwise rotation (according to sight unit scale).
