Once the measurement is complete, the result for the required dis-
tance X is displayed in the result row (d). The measured values for
distances 1 and 2 and angle α can be found in the measured value
rows (c).
Ensure that the reference level for the measurement (e.g. the rear
edge of the measuring tool) remains in exactly the same place for all
the individual measurements in a single measuring process.
c) Indirect length measurement (see figureI)
Select the indirect length measurement mode .
Ensure that the measuring tool is at the same height as the required measuring point.
Then tilt the measuring tool around the reference level and measure distance 1 as for a
length measurement.

Once the measurement is complete, the result for the required dis-
tance X is displayed in the result row (d). The measured values for
distance 1 and angle α can be found in the measured value row (c).
Wall area measurement (see figureJ)
The wall area measurement is used to determine the sum of multiple individual areas
with a common height. In the illustrated example, the total area of several walls that have
the same ceiling height H but different lengths L is to be determined.
Select the wall area measurement mode .
Measure the ceiling height H as for a length measurement. The measured value is dis-
played in the top measured-value line. The laser remains switched on.

Then measure the length L
1
of the first wall. The area is automatically
calculated and displayed in the result line (d). The last measured
value for length can be found in the bottom measured value line (c).
The laser remains switched on.
Now measure the length L
2
of the second wall. The individual meas-
ured value displayed in the measured value line (c) is added to the
length L
1
. The sum of the two lengths (displayed in the middle measured value line (c)) is
multiplied by the saved height H. The total area value is displayed in the result line (d).
You can measure any number of lengths L
x
, which will be automatically added and multi-
plied by the height H. The requirement for a correct area calculation is that the first
measured length (for example the ceiling height H) is identical for all sub-areas.
