2-44 Setting Up and Using Laser Alignment Fixtures
Note
There will, of course, be combinations of the movements shown in
the previous table. However, these recommendations should provide
some general guidelines.
Partial Sweep Rough Alignment
In this method, you must use the fixtures and set the analyzer to Manual Sweep or
Auto Sweep mode. Either method can provide an effective target area much larger
than the 20 mm x 20 mm surface area. If the fixtures can be rotated and both
beams remain on target greater than 90°
(recommended) of the sweep, the analyzer
can produce an alignment solution from the data taken. Data gathered from the
portion of the sweep that the laser beams were off target is rejected. For more infor-
mation about sweep data collection modes, see Chapter 6.
