White Level Calibration Service | 35
White Level Calibration Service
The white level of a Dome display is stabilized by the internal
RightLight photometer that is calibrated during display manufacture.
The White Level Calibration service allows the end user to calibrate
the sensor using an external photometer. When the calibration is
completed, the new calibration data file is stored in the display.
A one-time, end-user calibration of the white level may be necessary
when the target luminance is outside the tolerance established for
proper display conformance, such as when the white level of a display
has failed a manual conformance test, or when two or more displays
in a multi-unit configuration show disparate white levels. The
calibration may also be required for equipment changes, such as
when new external photometers are installed at your facility.
IMPORTANT: Only administrators can calibrate the white level via
the White Level Calibration service and restore factory calibration.
White level calibration via the White Level Calibration service is
available for use on all Dome CX and Dome EX displays. Restoration
of the factory white level calibration is available only for Dome E2,
Dome E3, Dome E3c, Dome E3cHB, and Dome E5 displays.
Privileged users can calibrate the white level during manual
conformance testing. For more information, see “To run a manual
conformance test” on page 24.
