Upon completion of the second measure-
ment, the surface is automatically calcu-
lated and displayed in the result line b.
The individual measured values are dis-
played in the measured-value lines a.
Volume Measurement (see figure D)
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 measure-
ment. The laser beam remains switched
on between all three measurements.
Upon completion of the third measure-
ment, the volume is automatically calcu-
lated and displayed in the result line b.
The individual measured values are dis-
played in the measured-value lines a.
Values above 999999 m
cated; "ERROR" appears on the display. Divide the volume to
be measured into individual measurements; their values can
then be calculated separately and then summarized.
Continuous Measurement (Tracking) (see figure E)
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 button 9 until the indi-
cator for continuous measurement
To start the continuous measurement, press the measuring
button 2.
The current measured value is displayed
in the result line b.
Pressing the measuring button 2 ends the
continuous measurement. The last meas-
ured value is displayed in the result line b.
Pressing the measuring button 2 again re-
starts a continuous measuring run.
Continuous measurement automatically switches off after
5 min. The last measured value remains indicated in the result
line b.
Indirect height measurement / Simple Pythagoras Meas-
urement (see figure F)
The indirect height measurement is used to measure distanc-
es that cannot be measured directly because an obstacle
would obstruct the laser beam or no target surface is available
as a reflector. Correct results are achieved only when the right
angles required for the respective measurement are exactly
adhered to (Pythagorean Theorem).
Pay attention that the reference plane of the measurement
(e.g. the rear edge of the measuring tool) remains exactly at
the same location for all individual measurements within a
measuring sequence.
The laser beam remains switched on between the individual
measurements.

Press button 3 until the indication for simple Pythagoras
measurement
Measure distances "1" and "2" in this sequence as for a
length measurement. Pay attention that a right angle exists
between distance "1" and the sought distance "X".
Deleting Measured Values
Briefly pressing button 4 deletes the last individual measuring
value determined in all measuring functions. Briefly pressing
the button repeatedly deletes the individual measured values
in reverse order.
Adding Measured Values
To add measuring values, firstly carry out a measurement.
Then press the plus button 8. For confirmation, "+" appears

cannot be indi-
on the display.
To add volumes or areas/surfaces, press the plus button 8 af-
ter the first completed measuring process. For confirmation,
"+" appears on the display left of the volume/area symbol.
Then carry out a second measurement.
appears on the display.
Notes on the addition:
– Mixed length, area/surface and volume values cannot be
added together. For example, when a length and area val-
ue are added, "ERROR" briefly appears on the display af-
ter pressing the plus button 8. Afterwards, the measuring
tool switches back to the last active measuring mode.
– For each calculation, the result of one measurement is
added (e.g. the volume value); for continuous measure-
ments, this would be the displayed measured value in re-
sult line b. The addition of individual measured values from
the measured-value lines a is not possible.

General Information
The reception lens 12 and the laser beam outlet 11 must not
be covered when taking a measurement.
The measuring tool must not be moved while taking a meas-
urement (with the exception of the continuous measurement

appears on the display.
Upon completion of the last measure-
ment, the result for the sought distance
"X" is displayed in the result line b. The in-
dividual measured values are displayed in
the measured-value lines a.
To call up the sum of both measurements,
press the plus button 8 again. The calcula-
tion is indicated in the measured-value
lines a, and the sum in the result line b.
After calculation of the sum, further
measured values can be added to this re-
sult when pressing the plus button 8 prior
to each measurement.
To subtract measuring values, press mi-
nus button 5; For confirmation, "–" is in-
dicated on the display. The further proce-
dure is analog to "Adding Measured
Values".
