Measuring Procedure
Once switched on, the measuring tool is in the length measure-
ment function. Other measuring functions can be set by pressing
the kbutton (see “Measuring Functions”, page 34).
Once the measuring tool has been switched on, the rear edge of
the measuring tool is selected as the reference level for measure-
ment. Press the ebutton to change the reference level (see “Se-
lecting the Reference Level”, page 34).
Place the measuring tool with the selected reference plane against the desired start-
ing point of the measurement (e.g. a wall).
To switch on the laser beam, briefly press the measuring button 1.
Do not point the laser beam at persons or animals and do not look into the la-
ser beam yourself, not even from a large distance.
Aim the laser beam at the target surface. To initiate the measurement, briefly press
the measuring button 1again.
In the function continuous measurement, the measurement begins the first time you
press the measuring button 1.
The measured value typically appears within 0.5 seconds and no later than 4 sec-
onds. The duration of the measurement depends on the distance, the lighting condi-
tions and the reflective properties of the target surface.
If no measurement has taken place approx. 20 seconds after sighting, the laser beam
is switched off automatically to save the batteries and the display is dimmed.

volumes and to automatically add or subtract them (e.g. helpful when calculating ma-
terials).
Press the kbutton and then select the button for length calculation or area
calculation or volume calculation .
Use the button to switch between “+” and “–” or to start a new calculation. To
complete the addition/subtraction, press the measuring button 1.
Values above 9999999 m3or below –999999 m3cannot be shown; “ERROR” ap-
pears on the display.
Indirect Distance Measurement
Note: Indirect distance measurement is always less accurate than direct distance
measurement. For application-relatedreasons, measuring errors can be greater than
with direct distance measurement. To improve measuring accuracy, we recommend
placing themeasuring tool againstor on a firm surface.
The indirect distance measurement is used to measure distances that cannot be
measured directly because an obstacle would obstruct the laser beam or no target
surface is available as a reflector. This measuring procedure can only be used in ver-
tical direction. Any deviation in horizontal direction leads to measuring errors.
For indirect length measurements, three measuring modes are available. Each meas-
uring mode can be used for determining different distances.

Working Advice
Themeasuringtoolisequippedwitharadiointerface. Local operating restric-
tions, e.g. in airplanes or hospitals, are to be observed.
General Information
The reception lens 9and the laser beam outlet 8must not be covered when taking a
measurement.
The measuring tool must not be moved while taking a measurement (with the excep-
tion of the continuous measurement and grade measurement functions). Therefore,
place the measuring tool, as far as this is possible,againstoronafirmstoporsupport-
ing surface.
Influence Effects on the Measuring Range
The measuring range depends upon the light conditions and the reflection properties
ofthetarget surface. For improved visibilityofthelaserbeam when workingoutdoors
and whenthesunlightisintense,usethelaserviewingglasses10(accessory) and the
laser target plate 11 (accessory), or shade off the target surface.
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be excluded when measuring on
different surfaces. Included here are:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal, glass),
– Porous surfaces (e.g. insulation materials),
– Structured surfaces (e.g., roughcast, natural stone).
If required, use the laser target plate 11 (accessory) on these surfaces.
Furthermore,faulty measurements are also possible when sighting inclined target
surfaces.
Also, air layers with varying temperatures or indirectly received reflections can affect
the measured value.

Accuracy Check and Calibration of the Grade Measurement
The tilt sensor is used in the “Inclination Measurement”, “Digital Spirit Level” and “In-
direct Distance Measurement” modes. When you are using these modes, we recom-
mend regular calibration (see “Basic Settings”, page 34). Follow the instructions on
the touchscreen.
We recommend that you perform an accuracy check and if necessary a calibration of
the measuring tool after extreme temperature variations and after impact to the tool.
After a temperature variation, the measuring tool must acclimatise for a while before
grade calibration is performed.
The measuring tool will automatically suggest a calibration after severe variations in
temperature.
Accuracy Check of the Distance Measurement
The accuracy of the distance measurement can be checked as follows:
– Select a permanently unchangeable measuring section which is approx. 3 to 10 m
long and which you know the exact length of (e.g. room width, door opening). The
measuring section must be indoors, and the target surface of the measurement
must be smooth and reflect well.
–Measurethedistance10 times after another.
The deviation of the individual measurements from the mean value must not exceed
±2 mm (max.). Log the measurements, so that you can compare their accuracy at a
later point of time.
Measuring with Positioning Plate (see figure B)
Using the positioning plate 3is suitable for applications such as measuring from a cor-
ner (room diagonal) or from hard-to-reach areas.
Fold out the positioning plate 3.
Set the reference level to measurement with positioning plate in the measuring tool.
When the measurement has been completed, fold the positioning plate 3back in.
