3BUS 208 000 R130144 Hardware Installation
Carriage Alignment
The mechanical alignment (relative positioning) of the sensor’s upper and lower
heads is critical in maintaining proper measurement characteristics. Both the static
(off-sheet) and the dynamic (scanning) alignments must be correct. Static and
dynamic alignment conditions (see Figure 3-10) which should be considered for
the sensor heads include the following alignments and adjustments:
• Pass Angle Adjustment (page 45)
• Process Direction (lateral alignment) (page 48)
• Air Gap Dimension (vertical spacing) (page 50)
• Scan Direction (horizontal alignment) (page 52)
These alignment and adjustment procedures are in the following sections.
