OPERATION
Intensity Power
Do not lower the " " so much that the corresponding " " value reaches
its minimum—the intensity setting will be inaccurate and cannot be maintained. For
best results in achieving uniform intensity amongst tiled images, choose an
Intensity
" " setting that enables all lamps to operate at less than the maximum number
of watts available in your projector but high enough to keep the corresponding lamp
Power
power above its minimum. See " ", above.
NOTES: 1) Lamps become more stable over time, thus a specific intensity is more
easily maintained as the lamp ages. 2) Intensity can be set only if the lamp is in
"Intensity" mode 3) Intensity cannot exceed the output of Max Brightness mode.
LAMP HISTORY -
This read-only option lists the most lamps most
recently installed and recorded in the projector. Lamp History
automatically updates whenever you record a new lamp serial
number—the new lamp is added to the bottom of the list.
CHANGE LAMP
Use to record the serial number for a newly installed lamp:
In the Lamp S/N window, use the number text entry keys to record the new lamp
serial number, and press again to accept the change. See Using Slidebars and
Other Controls if you need help entering the number. Once entered, the new lamp
serial number will be added to the Lamp History menu and the Lamp Hours timer
will reset to "0". Lamp Mode and Lamp Limit remain as they were for the previous
lamp, and can be changed at any time.
Figure 3.33. Recording the New Lamp Serial Number
NOTE: Enter a serial number only if you have just installed a new lamp. This will
help ensure that lamp timer is not reset on an old lamp and that the number of hours
logged on the lamp will be accurate.
IMPORTANT
Always DO record the serial number of a NEW lamp.
CABLE LENGTH (m) -
Use this slidebar to define what lengths of high voltage DC
cables are currently connected between the lamp ballast and the "Anode" and
"Cathode" ports on the rear of the projection head (refer back to Figure 3.31). This
regulates the voltage drop that occurs over distance, and ensures that adequate
voltage reaches the lamp. Particularly in projectors rented for temporary installations,
this setting may have to be changed from its last use. Adjustment range is 2-30m
(6½-100 ft.).
