1. Set up tripod with tribrach (only GDF111 or GDF121) as vertically as possible above the ground point.

3. Turn the base screws of the tribrach until the laser spot coincides with the ground point.

2. Insert basic laser plummet into the tribrach and switch on.

The basic laser

plummet can only be used together with one of the

and target point.

No objects between basic laser plummet

tribachs mentioned above.

accuracy is reached.

Always lock basic laser plummet SNLL111 in the

tribrach!

Page 12

Checking and Adjusting

Under normal circumstances adjusting the basic laser plummet is not necessary.

Checking by turning the instrument by 120°:

1. Install the instrument on the tripod and level up.

2. Switch on the basic laser plummet and mark the centre of the

red point on the ground.

3. Switch off the basic laser plummet, detach the basic laser

plummet from the tribrach and turn 120° about the plummet axis.

4. Mount the basic laser plummet back onto the tribrach and

switch on the basic laser plummet.

5. Mark the centre of the red point on the ground.

6. Repeat step 3 to 5 one more time.

At all time during the checking, the tribrach and the tripod must not be moved.

Checking the basic laser plummet must be carried out on a bright, even and horizontal surface (e.g. sheet of paper).

Laser spot: diam. 2.5 mm / 1.5 m

If the centre of the laser spot makes a clearly triangular movement or if the centre of the spot moves away more than 1.4 mm from the first marked point an adjustment may be necessary. Call your nearest Leica Geosystems service workshop.

Depending on brightness and surface the size of the laser spot can vary. At a distance of 1.5 m its average diameter is 2.5 mm.

26-BLL

The maximum diameter of the outer circle of triangular movement described by the centre of the laser spot should not exceed 1.6 mm at a distance of 1.5 m.

Care and Storage

Transport:

When dispatching the equipment, always use the complete original optional Leica Geosystems packaging. When transporting the equipment in the field, always make sure to:

• either carry the instrument in its original optional transport case

• carry the tripod with its legs splayed across your shoulders,

keeping the attached basic laser plummet (SNLL111) upright.

Remove batteries from the basic laser plummet when it

is shipped via rail, air or sea transport.

Storage:

When storing the equipment, particularly in summer and inside a vehicle, take the storage temperature limits (-40°C to + 70°C / -40°F to +158°F) into account.

Damp instruments must be unpacked. Dry the

instrument, the case, the foam inserts and the accessories at not more than 40°C / 108°F and clean them. Do not repack until everything is completely dry.

For long period of storage, remove batteries from the

instrument.

After a longer period of storage or transport of your

instrument, always perform the field adjustments indicated in this manual before using the instrument.

Cleaning and Drying

Objective, eyepiece and prisms:

• Blow dust off lenses and prisms.

• Never touch the glass with your fingers.

• Use only a clean, soft, lint-free cloth for cleaning.

If necessary, moisten the cloth with pure alcohol.

Use no other liquids; these may attack the polymer components.

Electromagnetic Compatibility (EMC)

The term "electromagnetic acceptability" is taken to mean the capability of the instrument to function correctly in an environment where electromagnetic radiation and electrostatic discharges are present, and without causing electromagnetic disturbances in other equipment.

WARNING:

Electromagnetic radiation can cause disturbances in

other equipment. Although the basic laser plummet meets the strict regulations and standards which are in force in this respect, Leica Geosystems cannot completely exclude the possibility that other equipment may be disturbed.

CAUTION:

Disturbances caused by electromagnetic radiation can

result in the tolerance limits for measurements being exceeded. Although the basic laser plummet meets the strict regulations and standards which are in force in this connection, Leica Geosystems cannot completely exclude the possibility that the basic laser plummet may be disturbed by very intense electromagnetic radiation, e.g. near radio transmitters, walkie-talkies, diesel generators, power cables. Check the plausibility of results obtained under these conditions.
