Displaying the Stored Value
Push the memory retrieve button 10 in order to dis-
play the value stored in the memory. "M=" is indi-
cated 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 2.
Deleting the Memory
To delete the memory contents, first push the memory retrieve button 10
so that "M=" is indicated in the display. Then push the delete button 1;
"M" is no longer indicated in the display.
Operating Instructions
The reception lens 17 and the laser beam outlet 16 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 measuring 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 conditions and the reflection
properties of the target surface. For improved visibility of the laser beam
when working outdoors and when the sunlight is intense, use the laser
viewing glasses 19 and the laser target plate 20 (accessories), or shade
off the target surface.
When measuring against transparent surfaces (e.g. glass, water) or reflect-
ing surfaces, faulty measurements are possible. Also, porous or structured
surfaces, air layers with varying temperatures or indirectly received reflec-
tions can affect the measured value. These effects are due to physical rea-
sons and can therefore not be excluded by the measuring tool.
Sighting with the Alingment Aid (see figure C)
With the alignment aid 7, 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.
