White Calibration - Konica Minolta CR-400 Instruction Manual

White Calibration

When using the instrument for long periods of time, the displayed value may change depending on
changes in the environment. Therefore, in order to achieve accurate measurements, we recommend
that white calibration is done regularly using the white calibration plate. White calibration should also
be done before measuring after a long time has passed since the instrument was last used.
White calibration should be done under the same temperature conditions as measurement.
