Measuring/Editing a Hue/Gray Reference
The reference function is used to enter hue error and grayness
reference data into the instrument. The reference data is stored
in the instrument until changed. Hue/Gray reference values
are then compared to Hue/Gray measurements and the
difference displayed. The instrument maintains separate
reference data for each of the filter values.
