A) The working range may be reduced by unfavourable environ-
mental conditions (e.g. direct sunlight).
B) Only non-conductive deposits occur, whereby occasional tem-
porary conductivity caused by condensation is expected.
The serial number (5) on the type plate is used to clearly identify your
measuring tool.
Fitting
Inserting/Changing the batteries
It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
To open the battery compartment cover(4), turn the locking
mechanism(3) clockwise to position and remove the
battery compartment cover. Insert the batteries.
When inserting the batteries, ensure that the polarity is cor-
rect according to the illustration on the inside of the battery
compartment.
To close the battery compartment cover(4), insert it below
the housing and then press it upwards into place. Turn the
locking mechanism(3) anticlockwise to position to lock
the battery compartment cover in place.
If the batteries are running low, the laser beams will flash
slowly. The measuring tool can be operated for approx.
8hours after the flashing starts.
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
uTake the batteries out of the measuring tool when you
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage.
Operation
Start-up
uProtect the measuring tool from moisture and direct
sunlight.
uDo not expose the measuring tool to any extreme tem-
peratures or variations in temperature. For example,
do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measur-
ing tool to adjust to the ambient temperature before put-
ting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperat-
ures or variations in temperature.
uAvoid substantial knocks to the measuring tool and
avoid dropping it. Always carry out an accuracy check
before continuing work if the measuring tool has been
subjected to severe external influences (see "Accuracy
Check of the Measuring Tool", page11).
uSwitch the measuring tool off when transporting it.
The pendulum unit is locked when the tool is switched off,
as it can otherwise be damaged by big movements.
Switching On/Off
To switch on the measuring tool, push the on/off switch(2)
upwards so that "I" is indicated on the switch. Immediately
after switching on, the measuring tool sends a laser beam
out of each outlet aperture(1).
uDo not direct the laser beam at persons or animals and
do not stare into the laser beam yourself (even from a
distance).
To switch off the measuring tool, push the on/off switch(2)
downwards so that "0" is indicated on the switch. The pen-
dulum unit is locked when the tool is switched off.
uNever leave the measuring tool unattended when
switched on, and ensure the measuring tool is
switched off after use. Others may be blinded by the
laser beam.
Setting the automatic switch-off
The measuring tool automatically switches itself off after
20min of operation.
The automatic switch-off can be set from 20minutes to
eighthours. For this, switch the measuring tool on, then im-
mediately off, and then on again within 4s. To confirm the
change, all laser beams will flash quickly for 2s after switch-
ing on the second time.
When switching on the measuring tool the next time, the
automatic switch-off is set to 20minutes again.
Automatic Levelling
Position the measuring tool on a level, firm surface or attach
it to the holder(8) or the tripod(16).
