7. The
laser
Head's
turret
ring should be
se
t to
"OT

"
during
installation, to take advantage
of
the s
tr
ongest possible beam,
which
this seni ng provides.
D
esc
ription
1. You will
init
ia
lly
position
the Optics in
their
relative positions
as
described in "
IMPOR
TANT
CONS
IDER
AT
ION
S", above, and
at
the ncar end
of
travel.
2.
You
will
position
the
la
se
r Head
so
the beam s
trik
es
the Optics.
NOTE
Two separate procedures will
be
provided for step "
1"
and step
"2
" above.
One
procedure
is for Vertical
axes;
the other is
for
Hori
zontal
axes.
3.
You
will
align the
la
se
r Head
to
track the Optic's progress
io
n along the travel path,
while
maintaining the beam's neaf*end*
of-Irave
l position. You will do this by -
• R
eviewing
the " GUNSIGHT" alignment
method
in
Sec
tion 15 of this
Use
r
's
Guide.
• Keeping the beam
within
the
Alignment
ring
on
the Straightn
ess
R
etror
efle
cto
r. to
maintain the beam's
near-end-of
travel position, and -
• Keeping a
two-dot
pattern in
lin
e with the junction
of
the
St
raightne
ss
Reflec
tor
's
mirrors, and
sy
mm
etrical about its s
lolled
openin
g,
to match the Optic's travel.
4.
fi
nall
y,
you
will
check your alignment to insure that " Important Considerati

have been met.
Installing
Optic
s For A Vertical-Axis Measurement
1. Assemble the S
tr
aightness Reflector and its
mount
as
you
wou
ld
for
a meas
urement
al
ong a
hori zontal
axis, except attach the post to the rear
of
the Adjustable
Mount
(
see
Figure 11-2).
Be
sure the Straig
htn
ess
Reflector's slot
is
oriented away from the
mounting
screw
s,
and
toward
where
the
Turnin
g
Mirror
will
be
mount
ed. (This is opposite
of
the way the Reflector
was
mount
ed
for
Str
ai
g
htn
ess
meas
urement
s along a Horizontal
axis,
described in
Sect

If
you
think
you will be
making
a Distance
or
Angular measure-
ment
later, establish a measurement
axis
at
a height above the
table that wi
ll
allow
easy
i
nt
erchanging
of
the
Opti
cs.
To
do this,
adjust the height
of
the Reflector/ Turning
Mirror
as
sembly to be
as
l
ow
as
po

le
on
its
Base.
