Digital Laser Measure
Dimensions
Degree of protection
A) The working range increases depending on how well the
laser light is reflected from the surface of the target (scat-
tered, not reflective) and with increased brightness of the la-
ser point to the ambient light intensity (interior spaces,
twilight). In unfavourable conditions (e.g. when measuring
outdoors at intense sunlight), it may be necessary to use the
target plate.
B) For measurements from the rear measuring-tool edge. In
unfavourable conditions (e. g. at intense sunlight or an insuf-
ficiently reflecting surface), a deviation influence of ±0.15
mm/m must be taken into account. In favourable conditions,
a deviation influence of ±0.05 mm/m must be taken into ac-
count.
C) In the continuous measurement function, the maximum
operating temperature is +40 °C.
D) The width of the laser line depends on the surface charac-
teristics and on the ambient conditions.
E) Less measurements are possible when using 1.2 V re-
chargeable batteries than with 1.5 V batteries. The battery
life listed refers to measurements without display illumina-
tion.
The measuring tool can be clearly identified with the serial
number 13 on the type plate.

Inserting/Replacing the Batteries

Using alkali-manganese or rechargeable batteries is recom-
mended for operation of the measuring tool.
Less measurements are possible when using 1.2 V recharge-
able batteries than with 1.5 V batteries.
To open the battery lid 10, press the latch 16 and remove the
battery lid. Insert the batteries/rechargeable batteries. When
inserting, pay attention to the correct polarity according to
the representation on the inside of the battery compartment.
When inserting the batteries/rechargeable batteries, pay at-
tention to the correct polarity according to the representation
on the inside of the battery compartment.
When the battery symbol
display, at least 100 individual measurements are still possi-
ble. The continuous measurement mode is deactivated.
When the battery symbol
able batteries must be replaced. Measurements are no longer
possible.
Always replace all batteries/rechargeable batteries at the
same time. Do not use different brands or types of batter-
ies/rechargeable batteries together.
 Remove the batteries/rechargeable batteries from the
measuring tool when not using it for longer periods.
When storing for longer periods, the batteries/rechargea-
ble batteries can corrode and self-discharge.
