Color Check Procedure
The ColorEye XTH comes with a Color Check Calibration Cap that allows you to monitor the
accuracy of your measurements and performance of your instrument.
You should perform the Color Check Procedure each day for the first 10 days of instrument
operation. Then the Color Check Procedure should be performed at a regular interval such
as every two weeks or every month.
Before you being the Color Check Procedure, you should fill in the information at the top of
the Color Check Record, shown below.
To perform the Color Check Procedure, proceed as follows:
1. Clean the Color Check Calibration Cap.
Refer to “Cleaning the Calibration Standards” on page 4-1.
2. Calibrate the instrument.
Refer to “Calibrating the Instrument” on page 4-2.
3. Select CIELAB as the Color Equation, D65 as the Illuminant, and 10
°
observer.
Refer to “Using the Color Setup” on page 2-4.
4. Measure the Color Check Calibration Cap.
Refer to “Taking Measurements” on page 1-12.
5. Record the L*a*b* values in the Color Check Record.
6. Compare the measured values to the reference values listed in your Certificate of
performance.
•
If values are off, clean the calibration standards (Color Check and White
Calibration Standards).
•
Consistent L*, a*, and b* differences or obvious trends away from the
reference data on the certificate may require the unit to be serviced.
Contact your X-Rite representative for advice.
•
Always verify color performance with the same aperture size and
temperature.
