Deleting Measured Values
Pushing the delete button 1 deletes the last individual
measuring value determined in all measuring func-
tions. Pushing the button repeatedly deletes the indi-
vidual measured values in reverse order.

Memory Functions

When switching off the measuring tool, the value in the
memory is retained.
Storing/Adding Measured Values
Push the memory add button 3
in order to store the current
measured value, – a length,
area or volume value, depend-
ing on the current measuring
function. As soon as a value
has been stored, "M" is indi-
cated in the display and the "+" behind it briefly
flashes.
If a value is already stored in the memory, the new
value is added to the memory contents, however, only
when the measures of unit correspond.
As an example, when an area value is in the memory
and the current measured value is a volume value, the
addition cannot take place. "ERROR" briefly flashes
in the display.
Subtracting Measured Values
Push the memory subtraction button 2 in order to sub-
tract the current measured value from the memory
value. As soon as a value has been subtracted, "M" is
indicated in the display and the "–" behind it briefly
flashes.
If a value is already stored in the memory, the new
measured value can be subtracted only when the
measures of unit correspond (see "Storing/Adding
Measured Values").
Displaying the Stored Value
Push the memory retrieve but-
ton 11 in order to display the
value stored in the memory.
"M=" is indicated in the dis-
play. When the memory con-
tents "M=" is indicated in the
display, it can be doubled by
pushing the memory add button 3 or set to zero by
pushing the memory subtract button 2.
Deleting the Memory
To delete the memory contents, first push the memory
retrieve button 11 so that "M=" is indicated in the dis-
play. Then push the delete button 1; "M" is no longer
indicated in the display.

Operating Instructions
The reception lens 20 and the laser beam outlet 19
must not be covered when taking a measurement.
The measuring tool must not be moved while taking a
measurement (with the exception of the continuous
measurement function). Therefore, place the measur-
ing tool, as far as this is possible, against or on the
measuring points.
Measurement takes place at the centre of the laser
beam, even when target surfaces are sighted at an
incline.
The measuring range depends upon the light condi-
tions and the reflection properties of the target sur-
face. For improved visibility of the laser beam when
working outdoors and when the sunlight is intense,
use the laser viewing glasses 22 and the laser target
plate 23 (accessories), or shade off the target surface.
When measuring against transparent surfaces (e.g.
glass, water) or reflecting surfaces, faulty measure-
ments are possible. Also, porous or structured sur-
faces, air layers with varying temperatures or indirectly
received reflections can affect the measured value.
These effects are due to physical reasons and can
therefore not be excluded by the measuring tool.
Sighting with the Alingment Aid (see figure G)
With the alignment aid 7, sighting over larger dis-
tances is a lot easier. For this, look alongside the align-
ing aid on the top side of the measuring tool. The laser
beam runs parallel to this line of sight.
Measuring with the Positioning Pin
(see figures B and H)
The positioning pin 14 is suitable for measuring out of
corners (diagonal within a space) or from hard to reach
areas, such as from roller-shutter rails.
Slide the latch 15 of the positioning pin sideward in
order to swivel out the pin.
Set the corresponding reference level for measure-
ments with the positioning pin by pushing button 10.
The positioning pin 14 swivels back in again by push-
ing it toward the housing to the stop. The pin automat-
ically locks in place.
Working with the Tripod
The use of a tripod is particularly necessary for larger
distances. The measuring tool can be screwed onto a
commercially available tripod using the 1/4" thread 21
on the bottom side of the housing.
Set the corresponding reference level for measure-
ment with a tripod by pushing button 10 (the reference
level is the thread).
