Color iQC Help - X-Rite

A second field, deCMC Limit, allows you to place a limit on how different each
reading can be from the average of all the readings; when this limit is passed, a
warning will appear in the Read dialog box. This function is disabled if this field is
left set to zero.
Calibration Interval --- This field determines the amount of time allowed
between calibrations of the instrument in the current mode.
Your name for this mode --- This field allows you to name the different
standardization modes defined for a particular instrument. Modes default to just
being numbered if you do not name them with the first being zero.
Calibrate
The instrument will need to be calibrated on a regular basis. You cannot
take measurements without calibrating the spectro or if the most current
calibration has expired.
Clicking on this menu option will bring up a small dialog box which will ask
you to read a certain number of check tiles or a light trap. The exact number of
tiles, their color, and the order you read them will depend on the type of
instrument you have and how it is set up. (Generally, a light trap and a white tile,
representing zero percent light and 100% light, are the minimum used in any
calibration.) See the documentation provided with your instrument for more
information about calibrating it.
Once you have read all the tiles requested, a final message box will
appear informing you that the instrument has been successfully calibrated.
Calibrating with a Colored Check Tile
GretagMacbeth highly recommends the use of a colored check tile during
the calibration process. Generally, this tile will be green or blue. Taking this
measurement in addition to using the light trap and a white tile helps to assure
the accuracy of measurements made by the spectro.
Once the use of the colored check tile during calibration has been set up,
the system will automatically prompt the user to read it after the light trap and
white tile have been measured. In fact, the system will inform you that the
calibration is complete through a small dialog box. When you click on the
button to close the message dialog, the system will open the check tile file along
with the Read dialog box. Instead of a name, the system will place the date and
time into the name field. Place the colored check tile over the instrument port and
take the reading. The measurement will be stored with the date/time information
as its name into the top of the trial data in the tree view. (The measurement will
be placed at the top of the trial portion of the tree view no matter how the system
is set to store other measurements.)
