Accessing automatic calibration validation information
You can request the measurement information from the last automatic calibration, which contains the RGB
patterns and the XYZ values measured by the instrument. If a StudioCal XML le was installed and contains
validation elements, it also includes the XYZ values measured post-calibration for the validation patterns
requested.
To download the data from the last calibration:
1. Insert a USB ash drive into one of the DreamColor USB ports. If the ash drive contains rmware or
StudioCal XML les, an on-screen message displays asking if you want to use them. Cancel any menus
that display.
2. Open the Calibration menu.
3. Select Export last calibration data.
The calibration data is written to the inserted USB ash drive.
Aligning the internal colorimeter to an external reference
instrument
The built-in XYZ colorimeter was aligned and calibrated at the factory against a Konica Minolta CA-310
instrument. While this alignment may be suitable for your needs, if you are deploying a number of displays,
you may want to align the internal colorimeter of those displays to a house reference instrument. Use the
Calibration menu for this task. See Using external measurement instruments on page 66 for more
information on the supported external instruments.
To align the internal colorimeter to an external reference instrument:
1. Allow the display to warm up for at least 30 minutes.
2. Ensure that the ambient lighting is set at the correct level: dim for a contact instrument and dark for a
noncontact instrument.
3. Connect the external instrument to use for alignment. Dismiss any calibration menus that display. If
using an X-Rite external instrument, adjust the position of the instrument and cord so they do not
interfere with the internal instrument arm’s operation.
4. Open the Calibration menu.
5. Select Align internal instrument to reference.
6. Select Align instruments. An alignment target is displayed.
7. Position the external instrument so that it is aligned with the target, and then press the Start
Alignment button.
The alignment will begin. If an error occurs, the display indicates whether the error occurred with the
external or internal instrument. If the error is with the external instrument, check the instrument’s
conguration and ensure that the ambient lighting is not too bright for the instrument type. If the error
is with the internal instrument, you may need to align the internal instrument’s position using the
provided menu option. This procedure takes about one minute and ensures that the motor start/stop
positions are correctly aligned so that the instrument is properly positioned in front of the display.
