Correcting Display Values to Match Actual Distances: Two-point Scaling A
Display values can be corrected if there is a discrepancy between the
actual distance from the Sensor Head to the sensing object and the value
displayed on the Amplifier Unit. When actual distances are known, they are
input at two points to correct the range and offset of display values (see fol-
lowing figure).
To change only the offset without changing the range of
display values, refer to
Offsetting Display Values: One-
