Setting a Color Difference Target Data
Setting a Color Difference Target Data
To measure the color difference between two specimens, the color of one of the specimens must be set
as the target color. Up to 1700 target colors can be set for color difference measurement. (700 can be set
in the “defined in COND” mode.)
To set a target color, follow the procedure given below.
M
emo
• Since tolerances for pass/fail judgment need to be set for each target color, target color data must be set before
setting tolerances.
• The memory of this instrument can store up to 1700 pieces of data in total, (700 in the “defined in COND” mode).
This amount includes the sample data for the COND and TASK modes as well as color difference target data.
When some sample data have already been stored, the number of target colors which can be set will be reduced
by the number of the sample data.
Note
• Before setting target colors, a measurement condition (COND1 to COND6) must be selected and white calibra-
tion performed.
• For accurate measurement, make sure to keep measurement conditions (ambient temperature etc.) constant.

Turn B to select “TARGET”, then press A.
• “T*” is the number of the color difference target data for the next measurement. If nothing is selected,
“T---” appears.
• “T*” does not appear if “defined in COND.” mode is selected.

Turn B to select D, then press A.
D will change to E.
• “T1” appears instead of “T---” if “defined in COND.” mode is selected.

Turn B to select the desired target color no. (T

), then press A.
E will return to D.
• Keeping B held down to left or right will cause the target color No. to change continuously.
