Protection rating
A) The working range may be reduced by unfavourable environ-
mental conditions (e.g. direct sunlight).
B) At 20–25 °C
C) The values stated presuppose normal to favourable environ-
mental conditions (e.g. no vibration, no fog, no smoke, no direct
sunlight). Extreme fluctuations in temperature can cause devi-
ations in accuracy.
D) Only non-conductive deposits occur, whereby occasional tem-
porary conductivity caused by condensation is expected.
The serial number (10) on the type plate is used to clearly identify
your measuring tool.

Inserting/Changing the batteries

3 601 K66 M..
It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
15 m
Press the locking mechanism (7) upwards to open the bat-
tery compartment cover (8) and remove the battery com-
5–50 m
partment cover. Insert the batteries.
When inserting the batteries, ensure that the polarity is cor-
10 m
rect according to the illustration on the inside of the battery
compartment.
±0.3 mm/m
The battery indicator (2) always indicates the current status
of the battery.
±0.7 mm/m
If the batteries are running low, the laser lines will gradually
±4°
become dimmer.
< 4 s
If the batteries are almost empty, the battery indicator (2)
–10 °C to +45 °C
will flash continuously. The laser lines will flash for 5 seconds
–20 °C to +70 °C
every 5 minutes.
If the batteries are empty, the laser lines and the battery in-
2000 m
dicator will flash once before the measuring tool switches
90%
off.
D)

Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
2
same capacity.

Take 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 in the measuring tool.
Protect the measuring tool from moisture and direct
sunlight.
Do not expose the measuring tool to any extreme tem-
peratures or fluctuations in temperature. For example,
do not leave it in a car for extended periods of time. If it
has been subjected to significant fluctuations in temper-
ature, first allow the measuring tool to adjust to the ambi-
ent temperature and then always carry out an accuracy
check before continuing work (see "Accuracy Check of
the Measuring Tool", page 17).
The precision of the measuring tool may be compromised
if exposed to extreme temperatures or fluctuations in
temperature.
Avoid 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", page 17).
Switch 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.
