4 times

(2) Teaching

Basically only one time measurement is necessary for each model for teaching, however when the optical
characteristics, etc. of the set are greatly changed, set the conditions again and measurement is neces-
sary again according to the changes.
Measurement method of the correction coefficient
(1) Determines the standard set of C55. 1 unit (n units)
(2) Set settings are RGB mode INPUT 1.
(3) Execute teaching in the following condition setting in that standard set.
