performance between fixtures. Dimmer and zoom are calibrated to defined points. The other effects are
calibrated relative to an arbitrary reference fixture.
All offsets can be set to
(the middle of their adjustment range) with the default offset command: select
→→→ then press [Enter].
To calibrate effects
1. Apply power but do not strike the lamp until zoom has been calibrated.
2. To calibrate zoom, first remove the bottom head cover. Select
→→ and press [Enter].
Adjust the offset until the face of the zoom lens plate is flush with the back edge of the focus plate. Press
[Enter] to save the setting. Replace the bottom head cover.
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
→→
and press [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
→→
and press [Enter]. Adjust the offset as necessary to align the beam with the reference beam. Press
[Enter] to save the setting.
5. To calibrate the dimmer, set the iris to fully closed and set focus to 1m in the
→ menu. Select
→→ and press [Enter]. Hold a piece of paper over the lens. Set the offset to zero and
then increase it until a clearly defined M shape with minimal light spill is projected onto the paper. Press
[Enter] to save the setting and remove the paper.
6. Focus calibration is useful when two or more fixtures are the same distance from a projection surface.
To calibrate focus, set up all fixtures with the same focus, zoom, dimming, iris, and gobo values. Select
a focused fixture to be the reference. On the other fixtures, select
→→ and press
[Enter]. Adjust the offset to focus the image. Press [Enter] to save the setting.
Fans
The cooling fans can be set to either full speed or thermostatically regulated operation via →.
In lower ambient temperature environments, regulated operation is recommended if reduced noise levels
are desired. Service life of lamps, fans, etc. is maximized if fans are set to full speed.
Software upload
The upload mode command (→) prepares the fixture for a software update. This command is
not normally necessary, as upload mode is engaged automatically by the uploader.
