Calibrating the CE7000A

The Color-Eye 7000A spectrophotometer needs to be calibrated with the white ceramic calibration tile provided with the unit. It is best to calibrate the instrument at the location it is to be used. This will accommodate ambient temperature changes.

Before You Calibrate…

- Calibration is required every 8 hours. It is a good practice to calibrate hourly.
- 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 Tile is the same as the serial number on the instrument. Do not substitute another calibration tile for the one originally supplied.
- If the tile should be broken or become damaged, call X-Rite for advice on how to replace it.

Reflectance Calibration Procedure

1) Touch and release "Cell 5" on the main menu display until the desired specular component status (SCE/SCI) is displayed.
2) Select the desired sampling aperture. Refer to “Changing the Sampling Aperture” on page 4-7 of the user manual.
3) Use the GretagMacbeth software program to select reflectance mode.
4) Place the Zero Calibration Standard facing the unit so that it completely covers the viewport opening.
5) Use the GretagMacbeth software program to initiate the zero (black) calibration.
6) Place the White Calibration Tile facing the unit so that it completely covers the viewport opening.
7) Use the GretagMacbeth software program to initiate the white tile calibration.
8) After calibration, return the white calibration tile to it storage area.

Transmission Calibration Procedure

1) Touch and release "Cell 5" on the main menu display until "Specular Component Included" displays.
2) Select the Large Area of View (LAV) sampling aperture and Large Area of View (LAV) Zoom Lens position. Refer to “Changing the Sampling Aperture” on page 4-7 of the user manual.
3) Place the Spectralon Calibration plaque facing the unit so that it completely covers the viewport opening.
4) Install the Thin Film / Transmission sample holder. (If a cuvette is to be used, insert a clean cell filled with distilled water in its holder.) Refer to “Using the Thin Film Sample Holder” on page 4-12 of the user manual.
5) Use the GretagMacbeth software program to select transmittance mode.
6) Use the GretagMacbeth software program to initiate the calibration.
7) After calibration, leave the Spectralon Calibration plaque in the viewport for the remainder of the measurements.
