n 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 n Offsetting Display Values: One-point
