Stadia
measurement.
There
are
two
pairs
of
short
hairs
on
the
graduated
plate
of
the
telescope,
i.e.
stadia
hairs.
They
are
used
to
measure
the
distance
between
the
target
to
be
measured
and
the
measurement
point
of
the
instrument.
Assume
the
distance
between
the
staff
and
the
measuring
point
is
D.
The
length
cut
by
a
pairs
of
the
stadia
hairs
on
the
scale
is
L
and
constants
of
the
stadia
are
K
and
C
which
are
100
and
0
respectively.
The
distance
measurement
formula
is
following:
D=KL+C-100L
Formula

Using
the
rotary
circle
mechanism.
Theodolites
Prof
X6
are
equipped
with
a
rotary
circle
knob
(6).
It
enables
the
reading
value
of
the
horizontal
graduated
circle
to
be
placed
in
the
direction
of
the
target
to
be
measured.
To
avoid
errors,
it
is
necessary
to
aim
at
the
target,
to
press
the
locking
catch
of
the
rotary
knob
(6)
and
press
the
knob
(6)
simultaneously.
Then,
rotating
the
knob
(6)
in
the
counter-clockwise
direction,
set
the
necessary
reading.
After
this
procedure
press
the
locking
catch
again
to
unlock
the
limb.
6.
ADJUSTING
THE
THEODOLITE
All
instruments
are
adjusted
and
checked
and
then
transported
to
users
after
careful
packing.
But
nevertheless
before
usage
it
is
necessary
to
repeat
the
adjustment
as
the
transportation
and
storing
conditions
may
tend
to
engender
the
possibility
of
deviation
from
correct
positions
adjusted
originally.
Such
adjustment
should
be
done
as
follows:
1.
Adjusting
the
tubular
level
of
the
alidade
Turn
the
alidade
so as
to
enable
the
tubular
level
to
be parallel
with
the
line
connecting
the
centers
of
any
two
of
foot
screws.
