I'm not getting the same numbers as I used to?
Please check the following:- Does your instrument display an error when calibrating?
- Are you sure that you are comparing numbers in the same numerical system; ie., Lab, Lch, etc.
- Are you using the same illuminant and observer settings?
- Do you have the aperture set correctly? (see Related Support)
- Have you tried resetting the instrument? (see Related Support)
If none of the above helps, the instrument requires service.
