In the comparison view, you see the older measurement, symmetry and trim data in red and the newer data in blue.
Here you can compare, how the changes on your trim have influenced the relative angle of incidence (AoI) and symmtery between two measurements.
You will also easily see, which loops have been adjusted or where changes like line inserts or cascade loops have been made.
The comparison protocol gives you a full overview of changes that have been done between two measurements, e.g. incoming inspection and final measurement, with timestamps.
This ensures that you have the full list of changes (such as line inserts, cascade loops and line comments) between the incoming inspection and your final validation measurement during a trim session, even if you did trimming and validation in multiple steps.
