Set brightness [06] to maximum (FF).
Measure amplitudes A, B, C, D, and E at #13 (Gout) as shown in the figure below. (A00 to E00)
Set green stretch [14] data to (08), and repeat the step 3 above. (A01 to E01)
Set green stretch [14] data to (10), and repeat the step 3 above. (A10 to E10)
Set green stretch [14] data to (18), and repeat the step 3 above. (A11 to E11)
