Calibrating the Instrument
The ColorEye XTH should be calibrated with the White Ceramic Calibration Standard (tile)
provided with the instrument in the pocket of the carrying strap. It is best to calibrate the
instrument at the location it is to be used. This will accommodate ambient temperature
changes.
Before You Calibrate
…
Please note the following before you calibrate the spectrophotometer:
•
If the instrument is exposed to rapid changes in ambient temperature, calibrate to
accommodate for these changes.
•
Make certain that the serial number on the White Ceramic Calibration Standard is
the same as the serial number on the instrument. Do not substitute another
calibration standard for the one originally supplied.
•
If the standard should be broken or become damaged, call X-Rite for
advice on how to replace it.
To perform a calibration, proceed as follows:
1. Select CAL from the ColorEye XTH Main Menu .
2. The following message appears:
