I get an error message when I calibrate my instrument

There are three possible error messages that may result from a failed calibration.

“Warning! Possible calibration error”

This message appears when the results of a calibration do not match the stored one. If you have calibrated your instrument on a different tile from the normal one (such as a mid-gloss tile) you can safely ignore this message.

Check that the instrument is correctly seated on the calibration tile and that the protective white tissue supplied with the instrument has been removed.

Check the tile and optics for contaminants. A residue-less solvent such as Iso-Propyl Alcohol can be used to clean these surfaces.

“Warning! Possible contamination”

This message appears on instruments that have a haze measurement function when the haze is higher than expected. If you are calibrating on a low-gloss tile, this message can be safely ignored. If this is done regularly, “Haze Tolerance” in the calibration menu can be set higher.

Check the instrument is correctly seated on the calibration tile, and the white tissue supplied with the instrument has been removed.

Check the tile and optics for contaminants. A residue-less solvent such as Iso-Propyl Alcohol can be used to clean these surfaces.

“Calibration Reference not set”

This means that the stored calibration has been lost or corrupted. The only function of the instrument that it will affect is calibration error detection. This message can be dismissed and the instrument used as normal. This issue will be resolved as part of a standard annual recalibration with an accredited service centre.
