Lamp Hours Progress Bar (Arc Models Only)
For arc models, there is a Lamp Hours Progress Bar representing lamp hours used on the lamp.
It is tied directly to the lamp hours within the MCB. The bar, when fully extended across the
full width of the menu display, represents 750 lamp hours (as indicated in
Figure 2
).
Resetting lamp hours will reset the progress bar. This bar is only for a quick graphical
representation of the lamp hours used. For actual lamp hours used, please read the following
note.
Note:
750 hours is the default setting for the Lamp Hours Progress Bar. However, the scale of
the progress bar is user definable by adjusting "Warning Hours" in [
Config]
. When the lamp
hours exceed the allotted (or defined) hours, the display will reverse contrast with a warning of
"Exceeded Lamp Hours".
