Technical terms and abbreviations, contd.
ci
Line-of-sight
error (Hz-
collimation)
The line-of-sight
error is the
deviation from
the perpendicular
between tilting
axis and line-of-
sight. This is
eleminated by
measuring in two
telescope
positions.
Zenith
Point on the
plumb line above
the observer.
Standing axis
inclination
Angle between
plumb line and
standing axis.
V-index (Vertical
index error)
With horizontal
line-of-sight the
V-curcle reading
should be exactly
90°(100gon). The
deviation from
this values is
termed V-index
(i).
Graticule
Glass plate
within the
telescope with
evaporated
reticle and
distance marks.
Plumb line /
Compensator
Direction of
gravity. The
compensator
defines the
plumb line within
the instrument.

Batteries
Your Leica Geosystems instrument is
operated with rechargable plug-in
batteries. The Basic battery
(GEB111) or the Pro battery
(GEB121) is recommended for T105/
T110 instruments. As an option, six
individual cells can be used with the
appropriate battery adapter GAD39.
Six individual cells (1.5 V each)
produce a voltage of 9 Volts. The
battery indicator in the display is
designed for a voltage of 6 Volts
(GEB111/GEB121). For this reason
the charge state of individual cells is
not indicated correctly. The battery
adapter with individual cells should
therefore be used as a backup. The
advantage of individual cells is the
low self-discharge rate - even over
longer periods of time.
Use the Leica Geosystems
batteries, chargers and
accessories or accessories
recommended by Leica
Geosystems to ensure the
correct functionality of the
instrument.

Inserting / Replacing Battery, continued
Insert battery correctly (note
pole markings on the inside
of the battery cover). Check and
insert battery holder true to side into
the housing.
• For type of battery see section
"Technical Data".
If the battery GEB121 or the
battery adapter GAD39 for
six individual cells is used, the spacer
for the GEB111 must be removed
from the battery holder prior to
inserting the battery.

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.
T100Z33
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.

5. Position tripod legs so that the
laser beam is aimed to the ground
point.
6. Firmly press in tripod legs.
7. Turn the footscrews of the tribrach
to centre the laser beam exactly
over the ground point.
8. Move the tripod legs to centre the
circular level. The instrument is
now roughly levelled-up.

Positioning over pipes or
depressions
In some cases the laser plummet
cannot be positioned because the
laser spot is not visible. In such
cases, place a transparent plate onto
the pipe. As a result, the pipe
perimeter remains visible and the
laser spot is reflected by the plate.
