Batteries

GEB111GEB121 Individual cells in the

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.

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.

T100z79

Use the Leica Geosystems
batteries, chargers and
accessories or accessories
recommended by Leica
Geosystems to ensure the
correct functionality of the
instrument.

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

Instrument errors

Line-of-sight error (Hz-collimation)

V-Index (Vertical index error)

The instruments are adjusted in the
factory prior to shipping.

Index-errors and line-of-sight errors
can change with time and
temperature.

These errors should be
determined before the
instrument is used for the first
time, before precision
surveys, after long periods of
transport, before and after
long periods of work, and if
the temperature changes by
more than 10°C (18°F).

C

The line-of-sight error or collimation
error (C) is the deviation from the
perpendicular between the tilting axis
and the line of sight.

The effect of the line-of-sight error to
the Hz-angle increases with the
vertical angle.
For horizontal aimings the error of Hz
equals the line-of-sight error.

T100Z16

The vertical circle should read
exactly 90° (100 gon) when the line
of sight is horizontal. Any deviation
from this figure is termed vertical
index error (i).

Hazards of use

Responsibilities of the person in
charge of the instrument:

WARNING:

The person responsible for

the instrument must ensure
that it is used in accordance with the
instructions. This person is also
accountable for the training and
deployment of personnel who use the
instrument and for the safety of the
equipment when in use.

The person in charge of the
instrument has the following duties:

• To understand the safety

instructions on the product and the
instructions in the User Manual.

• To be familiar with local regulations

relating to accident prevention.

• To inform Leica Geosystems

immediately if the equipment
becomes unsafe.

Main 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.

WARNING:

Using a battery charger not

recommended by Leica
Geosystems can destroy the
batteries. This can cause fire or
explosions.

Precautions:

Only use chargers recommended by
Leica Geosystems to charge the
batteries.

adjustments indicated in the User
Manual particularly after the
instrument has been subjected to ab­normal use and before and after
important measurements.

CAUTION:

Watch out for erroneous

DANGER:

Because of the risk of

electrocution, it is very
dangerous to use reflector poles 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.

CAUTION:

Be careful not to point the

instrument directly towards
the sun, because the telescope
functions as a magnifying lens and
can injure your eyes.

Precautions:

When viewing into the sun or against
bright objects only use suitable
accessories for this purpose.

Main hazards of use, contd.

WARNING:

During target recognition or

stakeout procedures there is
a danger of accidents occurring if the
user does not pay attention to the en­vironmental conditions around or
between the instrument and the
target (e.g. obstacles, excavations or
traffic).

Precautions:

The person responsible for the
instrument must make all users fully
aware of the existing dangers.

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:

If a target lamp accessory is

used with the instrument the
lamp's surface temperature may be
extreme after a long working period.
It may cause pain if touched.
Replacing the halogen bulb before
the lamp has been allowed to cool
down may cause burning to the skin
or fingers.

Precautions:

Use appropriate heat protection such
as gloves or woollen cloth before
touching the lamp, or allow the lamp
to cool down first.

CAUTION:

If the accessories used with

the instrument are not
properly secured, and the equipment
is subjected to mechanical shock
(e.g. blows, falling etc.), the
equipment may be damaged safety
devices may be ineffective or people
may sustain injury.

Precautions:

When setting-up the instrument,
make sure that the accessories (e.g.
tripod, tribrach, etc.) are correctly
adapted, fitted, secured and locked in
position.
Avoid subjecting the equipment 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.

Electromagnetic acceptability (EMV)

The term "electromagnetic

8

acceptability" is taken to mean the
capability of the instrument to

12

function correctly in an environment
where electromagnetic radiation and
electrostatic discharges are present,

15

and without causing electromagnetic
disturbances in other equipment.

31

WARNING:

Electromagnetic radiation
can cause disturbances in

other equipment.

Although electronic teodolites meet
the strict regulations and standards
which are in force in this respect, Lei­ca cannot completely exclude the
possibility that other equipment may
be disturbed.

CAUTION:

There is a risk that

disturbances may be caused
in other equipment if the teodolite is
used in conjunction with accessories
from other manufacturers (e.g. per­sonal computers, walkie-talkies, ...).

Precautions:

Use only the equipment and
accessories recommended by Leica
Geosystems. When combined with
teodolites, they meet the strict
requirements stipulated by the
guidelines and standards. When
using computers and walkie-talkies,
pay attention to the information about
electromagnetic compatibility
provided by the manufacturer.

CAUTION:

Disturbances caused by

electromagnetic radiation can
result in the tolerance limits for
measurements being exceeded.

Although the teodolites meet the
strict regulations and standards
which are in force in this connection,
Leica Geosystems cannot completely
exclude the possibility that the
teodolite may be disturbed by very
intense electromagnetic radiation,
e.g. near radio transmitters, walkie­talkies, diesel generators, power
cables.
Check the plausibility of results
obtained under these conditions.
