7. Pattern box
Before using the pattern box, turn its power on to carry out "Aging" approx. 30 minutes: the color temperature should
be adjusted to 3100 ± 20K by the color meter, and the luminance should be adjusted to 900 ± 20cd/m
2
by the
luminance meter. When the pattern box is used and for a while even after the power is turned off, the lamp and its
surroundings are subject to high temperatures, so handle them with care.
・ Procedure for calibrating Pattern Box
Note: Be sure to perform "aging".
1) Measure the measuring point (center of diffusion plate) with the Color Meter (J63081).
2) Adjust the pattern box so that the color temperature should be 3100 ± 20K by using "VR for adjustment of the color
temperature".
3) Measure the center of the diffusion plate with the Luminance Meter BM-3000 (J63068).
4) Adjust the pattern box so that the luminance should be 900 ± 20cd/m
2
by using "Knob for luminance adjustment".
5) Repeat from 1) to 4) so that the color temperature should be 3100 ± 20k and luminance should be 900 ± 20cd/m
