The knobs 1
The lower horizontal lock
clamps the H-circle and the
leveling head together
The lower slow motion
screw provides slow
controlled incremental
motion between the H-circle
and the leveling head
The knobs 2
With the upper
clamp still
locked to Be very
maintain our careful to not
zero setting disturb the
make sure the upper locking
lower clamp is clamp or slow
unlocked motion
tangent screw
Point the
telescope in the
general direction
of our BS target
BS 1
We may use the
peep sight to get
close
BS 2 peep sight
The target is in view and we
now need to lock the lower
clamp and use the lower
slow motion screw to put the
cross hairs on our target
<Lower lock
Cross hair on Bs 1
The knobs 4
We should now
unlock the upper
clamp
Upper Lock/Clamp>
Turn to the FS
get close with the
peep sight
<Vertical clamp
If you are also
reading the vertical
circle you must use <vertical slow motion screw
the Vert. Clamp
and slow motion
screw
<Upper horizontal lock/clamp
FS 2
Using the
peep sight
Close to target we may now
use the upper horizontal slow
motion screw and the vertical
slow motion screw to get on
target
Cross Hair on FS 1
We now need to
adjust the
micrometer knob
to accomplish
reading
FS 1 H mic 1
Turning the knob
FS 1 H mic 2
1) Do we have 3) Now to get V
coincidence ? You be reading we need to
the judge! readjust the
micrometer knob
To get coincidence
in the v window
FS 1 H mic 3
The vertical
circle readings
are referenced to
gravity
And the T1 has
an Auto
Compensator
So we do not
have to adjust
any bubbles
before reading
like we might
have to on some
other
instruments
Auto compensator 1
Auto compensator 2
Looks a little fuzzy –
maybe we should have
adjusted the micrometer
focus
Do we have coincidence in
the v box?

plunge the

We should
now unlock
the lower
clamp so that
we can carry
the previous
Hz reading to
the BS
RF BS 1
Using the
peep sight to
get close to
the BS
RF BS 2 peep sight
Lock the lower clamp and use the
lower slow motion screw to precisely
acquire the BS target
RF BS cross hair on
We can now
unclamp the
upper lock
knob and turn
the telescope
to point in
the direction
of our FS
target
RF FS 2 rough sight
Using the peep sight
RF FS 2 peep sight
With the upper clamp
now locked use the upper
slow motion tangent
screw to precisely acquire
the FS target in RF
RF FS 2 cross hair
We must now
turn the
micrometer knob
until the double
lines in the Hz
box are bisected
by the single
degree line from
the horizontal
circle
RF FS mic 1
There does this look
like we have
coincidence?

Now lets put
the instrument
away
Line up the
red dot and
red line
Lightly touch
…the two…
H-clamps to

Note the
resting places
for specific
