Storing/Adding Measured Values
Push the memory add button 3 in order to
store the current measured value – a length,
area or volume value, depending on the
current measuring mode.
As soon as a value has
been stored, “
M” is
indicated in the display
and “Add” is briefly
indicated next to it.
If a value is already stored in the memory, the
new value is added to the memory contents,
however, only if it’s the same type of
measurement.
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.
“Err.” briefly flashes in the display.
However, values of the same type (e.g. length
values) can be added no matter if they have
been measured in feet and inches, decimal
feet or meters.
Subtracting Measured Values
Push the memory
subtraction button
2 in
order to subtract the
current measured value
from the memory value.
As soon as a value has
been subtracted, “ M” is indicated in the display,
and is briefly followed by “Sub.”
If a value is already stored, then 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 button 11 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
2.
The memorized values can only be displayed
in decimal feet or meters.
Deleting the Memory
To delete the memory contents, first push the
memory retrieve button
11 so that “M=” is
indicated in the display. Then push the clear
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 rangefinder must not be moved while
taking a measurement (with the exception of
the continuous measurement mode).
Therefore, whenever possible, place the
rangefinder 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
22 and the laser target plate 23
(optional accessories), or shade off the target
surface.
When measuring against transparent surfaces
(e.g. glass, water) or reflecting surfaces, faulty
measurements are possible. Also, porous or
structured surfaces, 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 compensated for by the rangefinder.
Sighting with the Alignment Aid
(see figure G)
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
rangefinder. The laser beam runs parallel to
this line of sight.
Measuring with the Extension Pin
(see figures B and H)
The extension pin 14 is suitable for measuring
from inside corners (to measure diagonals) or
from hard to reach areas, such as from roller-
shutter rails.
