Degree of protection
A) The working range increases depending on how well the laser light is reflected from the surface of the target (scattered, not reflective) and with in-
creased brightness of the laser point to the ambient light intensity (interior spaces, twilight). In unfavourable conditions (e.g. when measuring out-
doors 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 insufficiently reflecting surface),
the maximum deviation is ±10 mm per 50 m. In favourable conditions, a deviation influence of ±0,05 mm/m must be taken into account.
C) In the continuous measurement function, the maximum operating temperature is +40 °C.
D) Less measurements are possible when using 1.2 V rechargeable batteries than with 1.5 V batteries. The battery life listed refers to measurements
without display illumination.
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
