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.

2. Turn footscrews of tribrach
into its centre position.
3. Centre circular level by
turning the foot screws.
Centring the circular level
1. Turn foot screws A and B
simultaneously in the opposite
direction until bubble is in the
centre (on the imaginary "T").

Focusing telescope
1. Aim telescope against a
bright background (e.g. white
paper).
2. Turn eyepiece until reticule is
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
Before starting field work
or after longer periods of
storage/transport of your
equipment check the field
adjustment parameters
specified in this User Manual.
Reduce possible
vibrations by holding the
tripod legs.
If the optical parts of
your instrument are dirty
of fogged, your measurements
can be affected. Keep clean all
optical parts of your instrument
and follow the cleaning
instructions specified in the
User Manual.
1. Setup instrument, level and
sharp-focus the reticule.
2. Setup level staff vertically
(refer also to Instruction
Manual of staff).
3. Roughly aim on staff using
the optical sight.
4. Sharp-focus using the
focussing knob.
Height reading
5. Fine-aim on staff using the
endless drives.
6. Check if circular level is
centred (view level prism).
7. Read off height H at the
centre hair of the reticule.
Example above:
H = 2.585 m

Wanted:
Height difference of several
reference points.
The required accuracy is
usually not very high
with such measurements.
Nevertheless, from time to time
read the staff on a stable
intermediate point (reading must
remain the same).
Area levelling
Procedure:
1. Set up instrument centrally
between the desired points.
The instrument telescope may
not be below the highest
measured intermediate point.
2. Set up staff vertically at
reference point A.
3. Aim on staff and read and
take down height (=backsight
to known point).
4. Set up staff vertically at
point 1.
5. Aim on staff and read and
take down height (=measuring
intermediate point,
intermediate sight)
6. Repeat steps 4 and 5 for
additional intermediate points.

Wanted:
Position of several ground
points.
The levelling total station
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 deter-
mined 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 (Hz-
direction).
4. Move staff to stakeout point
due to known values
(distance and Hz-angle,
height) and stakeout point.

Connection of individual
elements must always be tight.

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.

When transporting or
shipping the equipment
always use the original packa-
ging (transport case and ship-
ping cardboard).
After a longer period of
storage or transport of
your instrument always check
the field ajustment parameters
indicated in this manual before
using the instrument.
Care and Storage
In the field
When transporting the
equipment in the field, always
make sure to
• either carry the instrument in
its original transport case or,
• carry the tripod with its legs
splayed across your shoulder,
keeping the attached
instrument upright.
