of point 5) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the stan-
dard value.
4) Set the point 4 to the specified gradation. Set the correction value of G [(Initial value
of point 4) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the stan-
dard value.
5) Set the point 3 to the specified gradation. Set the correction value of G [(Initial value
of point 3) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the stan-
dard value.
6) Set the point 2 to the specified gradation. Set the correction value of G [(Initial value
of point 2) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the stan-
dard value.
7) Set the point 1 to the specified gradation. Set the correction value of G [(Initial value
of point 1) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the stan-
dard value.
8) Write the adjustment values with the MSET0003 command and turn off AC power.
