Calibration target panel” paragraph above. Verify that the sensor status field
states ‘CALIBRATED’.
Step 3: Calibration target
• Select the type of test patches to be used. Select ‘External computer graph-
ics’ if the host is the input source of the display and you want the want the
test patterns to be created in the calibration dialog. Select ‘Internal display
pattern generator’ when the display has an input source different from the
host. See the “User Interface, Sensor panel” paragraph for more details on
the selection of the test patch.
• Set the desired white point, mid gray, gamma and brightness by manually
changing the settings or load a previous set from file. See the “Sensor
panel” paragraph for details on calibration target settings and the paragraph
“Display connection and calibration” for specifics of the display.
Step 4: The calibration routine
• Press ‘Calibrate now…’ to open the calibration dialog.
• Follow the instructions as given in the calibration dialog and press ‘Start’ to
start the calibration routine.
• During the calibration routine, the user may interrupt at any time by press-
ing the ‘Close’ button to return to the main application.

Note that the display will not return to a previously known state but will leave the display in the
state that it was at the time of pressing the ‘Close’ button.
• The user is informed of each step of the calibration in the text area of the
calibration dialog.
• During calibration the progress bar is colored blue.
• When the calibration is finished, the progress bar will display if the calibra-
tion was successful or not and color green when successful, red if failed. The
same message will appear in the calibration status field of the main applica-
tion window. As soon as this message appears, you may close this dialog
box.
• If the dialog box is not closed after calibration, a verification process will
start. This process measures all gray levels in steps of 16 from 0 to 255 and
displays the measured results together with the desired values. See section
6 for details on the verification table.
• After the verification routine, the test patch will show a green color if the cal-
ibration was successful or red if it failed. Text in the text area of the calibra-
tion window can be copied and pasted into your favorite text editor and
saved to file.
• Press ‘Close’ to return to the main application. Pressing ‘Start’ will redo the
calibration routine all over again. If ‘Internal display pattern generator’ was
selected, the display will switch back to the previously selected input when
the calibration dialog is closed.
