With exception of the "Permanent laser beam" setting, all ba-
sic settings are retained when switching off.
Continuous 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.
In this setting, the laser beam also remains switched on be-
tween measurements; for measuring, it is only required to
press the measuring button 2 once.

Measuring Functions

Simple Length Measurement
For length measurements, press button 12 until the "length
measurement" indication appears on the display.
To switch the laser on and for measuring,
briefly press the measuring button 2 once
each time.
The measured value is displayed in the re-
sult line c.
For several subsequent length measurements, the last mea-
sured results are displayed in the measured-value lines a.
Area Measurement
For area/surface measurements, press button 12 until the in-
dicator for area measurement
Afterwards, measure the length and the width, one after an-
other, in the same manner as a length measurement. The laser
beam remains switched on between both measurements.
Upon completion of the second measure-
ment, the surface is automatically calcu-
lated and displayed in the result line c.
The individual measured values are dis-
played in the measured-value lines a.
Volume Measurement
For volume measurements, press button 12 until the indica-
tor for volume measurement
Afterwards, measure the length, width and the height, one af-
ter another, in the same manner as for a length measurement.
The laser beam remains switched on between all three meas-
urements.
Upon completion of the third measure-
ment, the volume is automatically calcu-
lated and displayed in the result line c.
The individual measured values are dis-
played in the measured-value lines a.

individual measurements; their values can then be calculated

inch, ft
For continuous measurements, the measuring tool can be
moved relative to the target, whereby the measuring value is
updated approx. every 0.5 seconds. In this manner, as an ex-
ample, you can move a certain distance away from a wall,
while the actual distance can always be read.
For continuous measurements, press function mode button 4
until the indicator for continuous measurement appears on
the display. To start the continuous measurement, press the
measuring button 2.
The minimum measurement is used to determine the shortest
distance from a fixed reference point. It is used, as an exam-
ple, for determining plumb lines or horizontal partitions.
The maximum measurement is used to determine the greatest
distance from a fixed reference point. It is used, as an exam-
ple, for determining diagonals.
The previous minimal and maximal values are deleted by
pressing the button for clearing the internal memory 8.
Pressing the measuring button 2 ends the continuous meas-
urement. The last measured value is displayed in the result

line c. Pressing the measuring button 2 again restarts a con-
tinuous measuring run.
Continuous measurement automatically switches off after
5 min. The last measured value remains indicated in the result
line c.
Indirect Distance Measurement
The indirect distance measurement is used to measure dis-
tances 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
vertical direction. Any deviation in horizontal direction leads
to measuring errors.
appears on the display.
The laser beam remains switched on between the individual
measurements.
For indirect length measurements, three measuring modes
are available. Each measuring mode can be used for deter-
mining different distances.
a) Indirect height measurement (see figure C)
Press the function-mode button 4 until the indication for indi-
rect height measurement

same height as the bottom measuring point. Now, tilt the

The current measuring value is displayed
in the result line c. The maximal ("max")
and the minimal ("min") measuring value

the present maximal value.
