FIRST-AXIS MEASUREMENT (Vertical
Axis Using
an Optical Square)
The
first-axis
measurement is a verti
ca
l
Straightness
measurement along a
vertical
axis.
It
will
be
similar to the
Straightness
measurement along
a vertical
axis
described
in Section
11,
except you
will use an Opti cal
Square,
and the
Straightness
Reflector will be oriented along a horizontal axis
rather than along the
vertical
axis.
(See
Figure
13-3.
)
