6-26 Acquiring Alignment Data
To acquire data using the Dual Pass method, you must first select Dual Pass
as the method from the Alignment Setup menu (accessed by pressing the
Options key). Once this method is shown, using the Up/Down Arrow keys
to select and the number keys on the keypad to toggle the selection, set the
Target Window percentage.
• Target Window - determines the size of the valid data window
around the vertical centerline of the other laser head's PSD. Use any
number keys on the keypad to toggle the Target Window between
10%, 25%, 50%, 75%, and 100%. The default is 100%.
Note
If a lower percentage (smaller valid window) is selected, a
slower rotational sweep speed may be required especially with
a smaller PSD (e.g. with the 10mm x10mm PSD on the 8215).
