<Setting the Color Difference Target Color>
Before measuring color difference, you must set the color difference target color in the measuring
head. 100 color difference target colors can be set to nos. T00 to 99.
The color difference target color number can be changed to a name for the sake of convenience.
The color difference target color number can be set independently of the page function (P.105).
Setting color difference target colors should be done under the same temperature conditions
as calibration and measurement.
There are two ways to set the color difference target color.
1) Measuring a specimen and setting the data as the color difference target color
2) Using the keys to set the color difference target color
