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 increased brightness of the laser 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. When meaning within 10m, measurement accuracy is ±2mm; more than 10m, measurement accuracy is calculated as
follows; ±2mm ±0.05 *(D-10) (D: Measuring Distance, Unit: m)
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 wit 1.5 V batteries.
E. In the continuous measurement function, the maximum operating temperature is +40 °C.
F. Less measurements are possible when using 1.2 V rechargeable batteries than with 1.5 V batteries.
ASSEMBLY
Inserting/Replacing the Batteries
Using alkali-manganese or rechargeable batteries is recommended for operation of the measuring tool.
Less measurements are possible when using 1.2 V rechargeable batteries than with 1.5 V batteries.
To open the battery lid 10, press the latch 9 in the direction of the arrow 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 the battery symbol
appears for the first time on the display, at least 100 measurements are still possible.
When the battery symbol flashes, the batteries/rechargeable 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
batteries/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/rechargeable batteries can corrode and self-discharge.
OPERATION
Initial Operation
Do not leave the switched-on measuring tool unattended and switch the measuring tool off after use. Other persons could
be blinded by the laser beam.
Protect the measuring tool against moisture and direct sun light.
Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it
in vehicles for longer periods. In case of large variations in temperature, allow the measuring tool to adjust to the
ambient temperature before putting it into operation.
Avoid heavy impact to or falling down of the measuring tool. After severe exterior effects to the measuring tool, it is
recommended to carry out an accuracy check each time before continuing to work.
