6-28 Acquiring Alignment Data
The typical method of operation will be for the user to initialize the laser
heads with the analyzer. One of the heads will then be moved to a new posi-
tion. Then the second head will be moved past the first head to a new posi-
tion. As the laser heads pass each other, the data will be acquired. The first
head will then be moved past the second head to a new position. Again, as
the laser heads pass each other, both laser heads will acquire the data. This
method continues until the user has acquired the necessary number of
passes and downloads the data to the analyzer. This may include several full
rotations of the laser heads.
Note
A minimum of three data points over a 45º sweep arc is
required, but CSI recommends a minimum of 8 data points
acquired over a sweep arc of at least 90º.
The current alignment method is always shown at the bottom center of the
main menu. Once the job has been defined and any soft foot has been cor-
rected (if necessary), prepare to measure the misalignment by selecting
Alignment Data from the Main Menu.
