Backsight/Foresight/
Intermediate sight
For determining the height
difference (∆H) between the
ground points A and B the back
sight (R) is measured first
followed by the forward sight
(V). Additional points relating to
A are measured as intermediate
sight (S).
Plumb line
By centring the circular level the
instrument is nearly levelled up.
A small instrument tilt remains
(the vertical axis tilt).
Compensator
The compensator in the
instrument is responsible for
compensating the vertical axis
tilt enabling an exactly horizontal
aiming.

When setting up the
tripod pay attention to a
horizontal position of the tripod
plate.
Heavy inclinations of the tripod
must be corrected with the
footscrews of the tribrach.
Setting up the tripod
1. Loosen screws of tripod legs,
pull out to required length and
tighten screws.
2. In order to guarantee a firm
foothold sufficiently press the
tripod legs into the ground.
When pressing the legs into
the ground note that the force
must be applied along the legs.
Careful handling of tripod
• Check all screws and bolts for
correct fit.
• During transport always use
the cover supplied.
Scratches and other damages
can result in poor fit and
measuring inaccuracies.
• Use the tripod only for
surveying jobs.

sharp-focussed and deep
black. Now the eyepiece is
adapted to your eye.
3. Aim telescope on staff using
the optical sight.
4. Turn focussing knob until
image of staff is sharply
focussed. If the eye is moved
up and down behind the
eyepiece the image of the staff
and the reticule may not be
displaced against each other.
For possible centring over a
ground point:
1. Attach plumb bob.
2. Loosen central fixing screw
slightly and shift instrument
parallel on tripod until the
plummet is exactly over the
point.
3. Tighten central fixing screw.

measuring is normally
carried out during area levelling.
Levelling total station measuring
Procedure:
1. Sequence of measurements
is the same as with area
levelling. However, beside the
height read also the staff
section L (see chapter
"Distance measuring") and
the Hz-angle.
2. Transfer measured value into
the map - points are determined by position and height.
Levelled stakeout
The stakeout is the counterpart
to the levelling total station
measuring - map points are set
out in the field.
Procedure:
1. Set up instrument at a known
point, centre and level up.
2. Focus instrument and aim on
known orientation point.
3. Orient horizontal circle (Hzdirection).

Checking and adjusting of the line-of-sight
With the circular bubble centred
and adjusted, the line of sight
should be horizontal.
Checking (see example):
1. Choose a distance of appr.
30 m within a gentle terrain.
2. Set up a staff at both final
points (A, B).
3. Set up the instrument at point
I1 (halfway between A and B,
just pass it down) and centre
the bubble.
4. Read both staffs.
reading on A = 1.832 m
reading on B = 1.616 m
∆H = A - B = 0.216 m
5. Set up the level about 1 m
from staff A
6. Read staff A (eg.: 1.604 m)
7. Find nominal reading B;
eg.: Reading A - ∆H =
1.604 m - 0.216 m = 1.388 m
8. Read staff B, compare
nominal-/actual- reading.
When the difference
nominal-/actual- reading
is more than 3 mm the line of
sight must be adjusted.
1. Turn the adjusting srew until
the midle hair gives the
required reading
(eg. 1.388 m).
2. Check line of sight again.

Hazards of use
WARNING:
The absence of
instruction, or the inadequate
imparting of instruction, can
lead to incorrect or adverse use,
and can give rise to accidents
with far-reaching human,
material, financial and environmental consequences.
Precautions:
All users must follow the safety
directions given by the
manufacturer and the directions
of the person responsible for the
instrument.
CAUTION:
Watch out for erroneous
measurements if the instrument
is defective or if it has been
dropped or has been misused or
modified.
Precautions:
Periodically carry out test
measurements and perform the
field adjustments indicated in
the User Manual particularly
after the instrument has been
subjected to abnormal use and
before and after important
measurements.
DANGER:
Because of the risk of
electrocution, it is very
dangerous to use levelling staffs
and extensions in the vicinity of
electrical installations such as
power cables or electrical
railways.
Precautions:
Keep at a safe distance from
electrical installations. If it is
essential to work in this
environment, first contact the
safety authorities responsible for
the electrical installations and
follow their instructions.

WARNING:
By surveying during a
thunderstorm you are at risk
from lightening.
Precautions:
Do not carry out field surveys
during thunderstorms.
Hazards of use, continued
WARNING:
Inadequate securing of
the surveying site can lead to
dangerous situations, for
example in traffic, on building
sites and at industrial
installations.
Precautions:
Always ensure that the
surreying site is adequately
secured. Adhere to the local
regulations governing accident
prevention and road traffic.
CAUTION:
Be careful when aiming
your level into the sun. Direct
sun radiation can hurt your

to mechanical shock.
Never position the instrument on
the tripod baseplate without
securely tightening the central
fixing screw. If the screw is
loosened always remove the
instrument immediately from the
tripod.
CAUTION:
When using a vertical
staff supported by one brace
there is always the danger of
falling (e.g. by wind gusts) and
therefore danger of damage to
equipment and danger of
personal injuries.
Precautions:
Never leave a vertical staff
supported by a brace
unsupervised (person at the
staff).
