d) Trapezium Measurement (see figure E)
The trapezium measurement can be used to determine the
length of a roof slope, for example.
Select the trapezium measurement .
Measure distances "1" , "2" and "3" in this sequence with a
length measurement. Pay attention that the measurement of
distance "3" starts exactly at the end point of distance "1" and
that a right angle exists between distances "1" and "2" as well
as between "1" and "3" .

Wall Area Measurement (see figure F)
The wall area measurement is used to determine the sum of
several individual surfaces with a common height.
In the illustrated example, the total area of several walls should
be determined, which have the same ceiling height H, but
different lengths L.
Select the wall area measurement
Measure the ceiling height H as with a length measurement.
The measured value is displayed in the top measured-value
line. The laser remains switched on.

Upon completion of the measurement, the result
for the sought distance "X" is displayed in the
48´06˝
result line a. The measuring values for the distance
60.0
"1" and the angle " " are displayed in the
measured-value lines h.
Upon completion of the last measurement, the
result for the sought distance "E" is displayed in

Then measure the length L1 of the first wall. The
surface is automatically calculated and displayed
8´02˝⅜
in the result line a. The last length measured value
41´02˝⅜
is in the bottom measured-value line h. The laser
12´09˝½
remains switched on.
