Adjustment of sRGB white
balance

1. Feed the RGB 50% grey pattern
signal.
2. Select the following group and
subjects.
Group: OUTPUT1
Subjects: S-R1-BLK, S-R1-GAIN,
SG1-
BLK, S-G1-GAIN, S-B1-BLK, SB1-
GAIN
3. Have the BM-5 brightness meter
and the standard white board at hand.

1. Make the S-R1-BLK setting the same as
the R1-BLK one.
Make the S-G1-BLK setting the same as the
R1-BLK one.
Make the S-B1-BLK setting the same as the
R1-BLK one.
Make the S-R1-GAIN setting the same as
the R1-GAIN one.
2. Adjust the S-B1-GAIN and S-G1-
GAIN settings so that the chromaticity on the
brightness meter should be as follows.
