Subtracting values
To subtract values, press the button (2) [–]. The subsequent steps are the same as for
the section on adding values.
List of the last measured values/calculations
The measuring tool stores the last 10 measured values and their calculations and dis-
plays them in reverse order (most recent measured value/most recent calculation first).
Press the button (6) to display the list of measured values.
Deleting measured values in the measured value list
Briefly press the on/off button (8) to delete the currently displayed measured value.
Press the button (6) and the on/off button (8) simultaneously to delete all measured val-
ues from the list.

Practical Advice

General advice
The reception lens (12) and the laser beam output (13) must not be covered during the
measuring process.
The measuring tool must not be moved while a measurement is being taken (unless in
continuous measurement mode). It is therefore advisable to place the measuring tool at
or on the measuring point.
The measurements are taken at the centre of the laser beam, even when the laser is poin-
ted at surfaces diagonally.
Influences on the measuring range
The measuring range depends on the lighting conditions and the reflective properties of
the target surface. For better visibility of the laser beam when working outdoors and in
bright sunlight, use the laser viewing glasses (15) (accessory) and the laser target plate
(16) (accessory) or shade the target area.
Influences on the measurement result
Due to physical effects, the possibility of inaccurate measurements when measuring vari-
ous surfaces cannot be excluded. These include:
– Transparent surfaces (e.g. glass, water)
– Reflective surfaces (e.g. polished metal, glass)
– Porous surfaces (e.g. insulating materials)
– Structured surfaces (e.g. roughcast, natural stone).
If necessary, use the laser target plate (16) (accessory) on these surfaces.
