Baseline Break

The baseline break feature modifies the appearance of the A-scan in full wave
rectified mode. When Baseline Break is active, the instrument identifies all "zero
cross" points as lines connecting individual A-scan lobes to the baseline on the
display. This feature can help to visually separate far surface defect echoes from the
back surface echo.
To activate the Baseline Break function
1. Choose Display Setup > Display Setup.
2. Set Baseline Break to On.
