Operation
f
Check the levelling and indication accuracy of the
measuring tool each time before using and after longer
transport of the measuring tool.
f
Protect the measuring tool against moisture and direct
sun light.
f
Do not subject the measuring tool to extreme tempera-
tures or variations in temperature.
As an example, do
not leave it in vehicles for long time. In case of large varia-
tions in temperature, allow the measuring tool to adjust to
the ambient temperature before putting it into operation.
In case of extreme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can be impaired.
f
Avoid any impact to or dropping of the measuring tool.
After severe exterior effects to the measuring tool, it is rec-
ommended to carry out an accuracy check (see “Accuracy
Check of the Measuring Tool”, page 10) each time before
continuing to work.
f
Place the measuring tool in the provided case when
transporting it over larger distances (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 intense movement.
Setting Up/Aligning the Measuring Tool
Mounting on the Tripod
Set up the tripod stable and safe against tipping over or slip-
ping off. Place the measuring tool via the tripod mount
13
on-
to 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 transport, 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 bub-
ble so that it is centred between 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 horizon-
tal 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 cen-
tre 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 tri-
pod 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 ob-
jective lens
1
. Turn the eyepiece
6
until the
crosshair appears sharp and deep black.
