Adjusting Lamp Position (Lamploc™) - Christie CP2000-M User Manual

Adjusting Lamp Position (LampLOC™)
LampLOC™ not being performed, there may be damage to the optical system. If these
symptoms are observed, immediately contact Christie Technical Support staff.
Align a newly-installed lamp as soon as possible to ensure optimized lamp performance and peak brightness at
the screen for the life of the lamp. NOTES: 1) Before adjusting, a 10-minute warm-up is recommended.
Follow all criteria specified in
either before or after adjustment of Lamp Power or LiteLOC.
Use the "Do Auto" Button for LampLOC
For best results in all installations, align the lamp by pressing the
menu. The motors and sensors in the projector work together to precisely position the lamp for optimized
performance and brightness, utilizing filtering to eliminate signs of lamp flicker. Once aligned, this
LampLOC setting can be considered fairly stable for the life of the lamp. TIP: On-screen uniformity can be

improved after using Do Auto by manually adjusting the Z-axis motor. Brightness efficiency is decreased a very
small amount when this is done.
When to use the individual LampLOC buttons:
The individual LampLOC
reassuring back-up should the
result in more output or improved brightness uniformity. Either measure the results with a light meter at the
lens and screen or simply watch the light output gauge in the Advanced: Lamp menu. NOTE: These buttons
may attain a slightly higher peak than when using the Do Auto button, but the peak may not be centered on the
lamp curve and lamp performance may not be optimized (whereas the Do Auto button also utilizes filtering to
eliminate the effects of any lamp flicker). In general, use the individual buttons only when unavoidable.
How to adjust (if using a light meter):
Obtain peak readings on a light meter centered in front of the lens, then at the center of the screen. For each
button, continue in one direction, then back-up when reading begins decreasing. 
NOTES: 1) Display a 100% white internal test pattern. 2) Use a tripod to center the light meter with the lens.
Distance from the lens does not matter. You may need an attenuator, or wish to construct an internal foil
aperture first. 3) This is an optional procedure—use the light output gauge in the Advanced: Lamp menu if
preferred. 4) After performing LampLOC (Do Auto), brightness uniformity may also be improved on some
lamps by manually adjusting the Z-axis motor control. In some instances, this may cause a reduction in overall
brightness.
1. Adjust forward/aft (Z) until the brightness reading in front of the lens is maximized.
2. Adjust left/right (X) and up/down (Y) until the brightness reading in front of the lens is maximized.
3. Re-adjust forward/aft (Z), as necessary.
4. Repeat Steps 1-3, as necessary.
5. Repeat Steps 1-4, but reading at the screen instead of at the lens.
6. Reset Lamp Power or LiteLOC
