set by selecting [EXECUTE] button and pressing [OK] key.

(Example)
The following is the case where the adjustment value or the set
value is fixed by selecting [EXECUTE] button and press [OK] key.

d. Item selection by the item number
A target item on the simulation menu is selected by the number
which is assigned to the item.
