Difference Area
A Difference Area measurement determines the difference in cross-sectional area between live profile

yield a decision.
To create or edit a Difference Peak measurement:

2
Adjust the measurement region.
The measurement region defines the zone in which cross-sectional area will be determined.
3
Provide minimum and maximum constraints for a decision.
Refer to the Decisions section (page 74) in this chapter for more information on decisions.
The difference can be calculated as an absolute or signed.
The result is the sum of all the areas within the measurement region.
