3.6.4 Calibrating Screen Brightness (fL)

In order to determine the screen brightness in footlamberts (fL), you must measure the screen brightness at
both extremes of the lamp power (minimum and maximum) for a given lamp type and record these two
readings using the Foot Lamberts Calibration window at Administrator Setup: Foot Lamberts
Calibration. See the
measurements establish a range (stored in memory) from which the projector can interpolate all other lamp
power settings by converting them to approximate footlamberts for display in the appropriate TPC windows.
Repeat the calibration if you switch to a different lamp type/size.

3.6.5 Age of a Lamp

When to Replace a Lamp
When a new lamp is installed and its serial number recorded, the lamp timer defaults to "0" and begins logging
time for the new lamp. If installing a used lamp, enter the number of hours when adding the lamp for the timer
to begin logging at the time specified. When replacing the lamp, be sure to specify the lamp expiry hours. For
all lamp information and the ability to replace a lamp, navigate to the Advanced Setup: Lamp History
window.
Assuming the Lamp Expiry check box is selected in the Administrator Setup: Preferences window
(recommended), an expiry message will appear as an alarm window when the lamp has reached its defined
Lamp Expiry limit and should be replaced. For details on replacing a lamp, see
4-7. DANGER! 1) It is recommended that you set Lamp Expiry based on the average lifetime of the
page
lamp, as older lamps become increasingly fragile and more prone to sudden failure or even explosion, which
can be damaging and dangerous. 2) Lamp replacement must be performed by qualified service technicians
only.
These maximum limits appear in the table below:

Lamp Rotation
When the lamp reaches mid-life, a Lamp Rotation message may appear as an alarm window to indicate the
bulb should be physically rotated 180° to ensure an even burn of the lamp. For the alarm window to display,
ensure the Lamp Rotation check box is selected in the Administrator Setup: Preferences window. Rotating
the lamp improves its performance and life expectancy. Lamp rotation requires the same safety precautions as
