Set the reference values in either of two methods:
5-2-1. Use the measured values and adjust it manually
as the reference values.
5-2-2. Use previous values stored in memory and adjust
manually as the reference values.
The difference between method 5-2-1 and 5-2-2 is whether
the Data Hold was enabled before entering the set mode.
Note:
Color difference = (Measured value) – (Reference value)
