2.5.1 Calibrating Screen Brightness (fL)

(Using the Web User Interface)

In order to determine screen brightness in footlamberts (fL), you must measure screen brightness at both

extremes of lamp power (minimum and maximum) for a given lamp type, and record these two readings in

Admin: Lamp menu. See Figure 2-21. These measurements establish a range (stored in memory) from which

the projector can interpolate all other lamp power settings, converting them to approximate footlamberts for

display in the menus. Repeat the calibration if you ever switch to a different lamp type/size.

2.6 Basic Image Alignment

NOTE: Assumes projector is fully assembled and powered up in its final location.

This procedure ensures that the image reflected from the DMDs is parallel to and well-centered with both the

lens and screen. This initial optical alignment is the foundation for optimizing images on the screen, and must

be completed before final boresight adjustments.

Make sure the CP2000-ZX is properly positioned relative to the screen before you begin.
