Displaying the Stored Value
Push the memory retrieve
button 2 in order to display
the value stored in the
memory. "M=" is indicated
in the display. When the
memory contents "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 12.
Deleting the Memory
To delete the memory contents, first push the
memory retrieve button 2, so that "M=" is indi-
cated in the display. Then briefly press button
14; "M" is no longer indicated in the display.

Working Advice

General Information
The reception lens 22 and the laser beam outlet
21 must not be covered when taking a measure-
ment.
The measuring tool must not be moved while
taking a measurement (except for the functions
minimum/maximum measurement incl. continu-
ous measurement). Therefore, place the meas-
uring tool, as far as this is possible, against or on
the measuring points.
Measurement takes place at the centre of the la-
ser beam, even when target surfaces are sighted
at an incline.
Influence Effects on the Measuring Range
The measuring range depends upon the light
conditions and the reflection properties of the
target surface. For improved visibility of the la-
ser beam when working outdoors and when the
sunlight is intense, use the laser viewing glasses
24 (accessory) and the laser target plate 25 (ac-
cessory), or shade off the target surface.

Influence Effects on the Measuring Result
Due to physical effects, faulty measurements
cannot be excluded when measuring on differ-
ent surfaces. Included here are:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal,
glass),
– Porous surfaces (e.g. insulation materials),
– Structured surfaces (e.g., roughcast, natural
stone).
If required, use the laser target plate 25 (acces-
sory) on these surfaces.
Furthermore, faulty measurements are also pos-
sible when sighting inclined target surfaces.
Also, air layers with varying temperatures or in-
directly received reflections can affect the
measured value.
Measuring with the Positioning Pin
(see figures C, F and G)
The positioning pin 15 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 16 of the positioning pin side-
ward in order to swivel out the pin.
Set the corresponding reference level for meas-
urements with the positioning pin by pushing
button 1.
The positioning pin 15 swivels back in again by
pushing it toward the housing to the stop. The
pin automatically locks in place.
Aligning with the Spirit Level
The spirit level 6 allows for simple levelling of
the measuring tool. This allows for easier sight-
ing of target surfaces, especially over longer dis-
tances.
In combination with the laser beam, the spirit
level 6 is not suitable for levelling.
Sighting with the Alingment Aid (see figure K)
With the alignment aid 8, sighting over larger
distances is a lot easier. For this, look alongside
the aligning aid on the top side of the measuring
tool. The laser beam runs parallel to this line of
sight.
