f

Avoid any impact to or dropping of the 
measuring tool. 

After severe exterior effects 

to the measuring tool, it is recommended to 
carry out an accuracy check (see “Accuracy 
Check of the Measuring Tool”, page 13) each 
time before continuing to work.

f

Place the measuring tool in the provided 
case when transporting it over larger dis-
tances (e. g. in the car). Ensure that the 
measuring tool is correctly placed in the 
transport case. 

When placing the measuring 

tool in the case, the compensator is locked; 
otherwise, it could be damaged in case of in-
tense movement.

Setting Up/Aligning the Measuring Tool

Mounting on the Tripod

Set up the tripod stable and safe against tipping 
over or slipping off. Place the measuring tool via 
the tripod mount 

13

 onto the male thread of the 

tripod and screw the measuring tool tight with 
the locking screw of the tripod.
Roughly level the tripod.
Over short distances, the measuring tool can be 
carried mounted on the tripod. To ensure that 
the measuring tool is not damaged during this, 
the tripod must be held vertically during trans-
port, and should not be carried lengthwise over 
the shoulder.

Aligning the Measuring Tool

Align the measuring tool with the levelling 
screws 

12

 so that the air bubble is positioned in 

the centre of the circular bubble vial 

7

. 

Turn the first two levelling screws 

A

 and 

B

 to 

move the air bubble so that it is centred be-
tween the two levelling screws. Then turn the 
third levelling screw 

C

 until the air bubble is po-

sitioned in the centre of the circular bubble vial.

Any remaining deviation of the measuring tool to 
the horizontal plane following the balancing of 
the circular bubble vial is compensated by 
means of the compensator.
While working, regularly check (e. g. by viewing 
through the bubble vial mirror 

3

) whether the air 

bubble is still in the centre of the circular bubble 
vial.

Centring the Measuring Tool over a Point on 
the Ground 

If required, centre the measuring tool over a 
point on the ground. For this, hang the plumb-
bob 

20

 onto the locking screw of the tripod. 

Align the measuring tool above the point on the 
ground either by moving the measuring tool on 
the tripod or by adjusting the tripod.

Focusing the Telescope

Remove the lens cap from the objective lens 

1

.

Direct the telescope against a bright 
object or hold a white sheet of paper 
in front of the objective lens 

1

. Turn 

the eyepiece 

6

 until the crosshair ap-

pears sharp and deep black.

Direct the telescope towards the levelling rod, if 
required with help of the optical peep sight 

2

. 

Turn the focusing knob 

16

 until the graduation 

field of the levelling rod appears sharp. Align the 
crosshair exactly with the centre of the levelling 
rod by turning the horizontal drive screw 

14

.

When the telescope is correctly focussed, the 
crosshair and the image of the levelling rod must 
remain aligned when moving your eye behind 
the eyepiece.

Measuring Functions

Always set up the levelling rod exactly vertical. 
Direct the aligned and focussed measuring tool 
against the levelling rod in such a manner that the 
crosshair faces centrally against the levelling rod.
