Selecting the Reference Level (see figures A–C)
For measuring, you can select between three different reference levels:
– the rear measuring-tool edge (e.g. when measuring onward from a wall),
– the rear positioning-pin edge 14 (e.g. when measuring from a corner),
– the front measuring-tool edge (e.g. when measuring onward from a table
edge).
To change the reference level, press button 9 until the requested reference level
is indicated on the display. Each time after switching on the measuring tool, the
rear end of the measuring tool is preset as the reference level.

Measuring Functions

Length Measurement
For length measurement, push button 1. The indicator for length measurement
appears in the display
Area Measurement
For area/surface measurements, press button 3 until the indicator for area
measurement appears on the display.
Afterwards, measure the length and the width, one after another, in the same
manner as a length measurement. The laser beam remains switched on be-
tween both measurements.
Volume Measurement
For volume measurements, press button 3 until the indicator for volume
measurement appears on the display.
Afterwards, measure the length, width and the height, one after another, in the
same manner as for a length measurement. The laser beam remains switched on
between all three measurements.
Indirect Length Measurement (see figure D)
The indirect length measurement is used to measure distances that cannot be
measured directly because an obstacle would obstruct the laser beam or no tar-
get surface is available as a reflector. Correct results are achieved only when the
laser beam and the sought distance form an exact right angle (Pythagorean The-
orem).
In the illustrated example, the length B is to be determined. For this purpose, A
and C must be measured. A and B must form a right angle.
For indirect length measurements, press button 5. The indicator for indirect
length measurement appears on the display

.
Push the measuring button 12 once for sighting and
once more to take the measurement.
The measured value is indicated at the bottom in the
display.
After taking the second measurement, the area/sur-
face is automatically calculated and displayed. The
last individual measured value is indicated at the bot-
tom in the display, while the final result is shown at
the top.
After taking the third measurement, the volume is
automatically calculated and displayed. The last indi-
vidual measured value is indicated at the bottom in
the display, while the final result is shown at the top.
