3 Pan calibration is most useful when multiple fixtures are stacked vertically. To calibrate, set zoom, focus, iris,
and tilt position for easy one-over-the-other comparison and set each fixture to the same pan DMX value.
Select one fixture to be the reference fixture. On the other fixtures, select
[Enter]. Adjust the offset as necessary to align the beam with the reference beam. Press [Enter] to save the
setting.
4 Tilt calibration is most useful when multiple fixtures are arranged horizontally. To calibrate, set zoom, focus,
iris, and pan position for easy side-by-side comparison and set each fixture to the same tilt DMX value.
Select one fixture to be the reference fixture. On the other fixtures, select
