Correcting Display Values to Match Actual Width: Two-point Scaling A
Display values can be corrected if there is a discrepancy between the
actual incident beam width and the value displayed on the Amplifier Unit.
When actual widths are known, they are input at two points to correct the
range and offset of display values (see following figure).
To change only the offset without changing the range of
display values, refer to
Offsetting Display Values: One-

Despite the actual 2.0-mm incident
beam width, 2.2 mm is displayed.

In addition, despite the actual 4.0-mm
incident beam width, 3.6 mm is displayed.
