Operation

Initial Operation

Protect the measuring tool against moisture
and direct sun irradiation.
Do not expose the measuring tool to extreme
temperatures or variations in temperature.
Switching On and Off
To switch on the measuring tool, briefly press
the On/Off button 13 or measuring button 9.
When switching on the measuring tool, the laser
beam is not switched on yet.
To switch off the measuring tool, press the
On/Off button 13 for a few seconds.
If none of the measuring tool buttons are pressed
for approx. 5 minutes, the measuring tool switch-
es off automatically in order to extend the service
life of the battery.
When a measured value has been stored, it is
retained in automatic switch-off mode. When
switching on the measuring tool again, "M" is
indicated in the display.
Measuring Procedure
After switching on, the measuring tool is in the
length measurement mode. Other measuring
modes can be switched to by pressing the re-
spective function/mode button (see "Measuring
Functions", page 19).
After switching on, the rear edge of the measur-
ing tool is preset as the reference level for the
measurement. By pressing the reference level
button 1, the reference level can be changed (see
"Selecting the Reference Level", page 18).
Upon selection of the measuring function and the
reference level, all further steps are carried out
by pushing the measuring button 9.
With the reference level selected, place the
measuring tool against the desired measuring
line (e.g. a wall).
Briefly press the measuring button 9 to switch on
the laser beam.
Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a large distance.

Aim the laser beam at the target surface. Briefly
press the measuring button 9 again to initate the
measurement.
In the continuous measurement mode, the meas-
urement begins immediately upon switching on
the function.
Typically, the measured value appears after 0.5
and latest after 4 seconds. The duration of the
measurement depends on the distance, the light
conditions and the reflection properties of the
target surface. The end of the measurement is
indicated by a signal tone. The laser beam is
switched off automatically upon completion of
the measurement.
When no measurement has taken place approx.
20 seconds after sighting, the laser beam is
switched off automatically to save the batteries.
Selecting the Reference Level (see figure B–C)
Two different reference levels are available for
measuring:
– The rear edge of the measuring tool
(e.g. when placing against a wall),
– The front measuring-tool edge (e. g. when
measuring onward from a table edge).
To change the reference level, press button 1
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.
Changing the Unit of Measure
The unit of measure can be changed any time for
display of the measured values, even for already
measured or calculated values.
For display of the current
length measurement values,
the units of measure shown
opposite are available.
Area and volume values as
well as stored measured
values can only be dis-
played in "ft" or "m".
To change the unit of measure, push button 12
until a new unit of measure is displayed.
The unit-of-measure setting is retained when
switching the measuring tool on or off.
