6.7.10.2 Reduced measuring range
Measuring range may be reduced in bright conditions,
e.g. in bright sunlight or when working under very power-
ful floodlights.

7 Operation

NOTE
The direct control buttons are used for adding and sub-
tracting distances. All other functions are activated by
pressing the FNC-button.
7.1 Distance measurements
NOTE
With all functions of the tool, each step in the operation
is always indicated in the display.
NOTE
Continuous measuring mode can be used with all func-
tions in which individual distance measurement is pos-
sible.
NOTE
If measuring errors occur during continuous measuring,
and continuous measuring mode is canceled by pressing
the "Measure" button again, the last valid measurement
will be displayed.
7.2 Adding distances
+
17.838
Individual distances can be conveniently added. This is
useful, for example, for determining the total length of
the inner face of door or window openings or for adding
several individual distances that form a perimeter.
1. Press the "Measure" button (the laser beam will
switch on).
2. Aim the range meter at the target.

The range of the tool may be reduced when measure-
ments are taken through glass or when objects lie within
the path of the laser beam.
The range of the tool may be reduced when measure-
ments are taken to mat green, blue or black surfaces or
to wet or shiny surfaces.
3. Press the "Measure" button.
The first distance will be measured and displayed
(the laser then switches off).
4. Press the "Plus" button. The first distance is then
displayed in the middle result line and a plus sign
appears in the lower (intermediate) result line (the
laser beam switches on).
5. Aim the range meter at the target.
6. Press the "Measure" button.
The second distance is then measured and dis-
played in the lower (intermediate) result line. The
result of the addition is shown in the result line.
The current total of the distances is always shown
in the result line.
The procedure can be repeated until all distances
have been added.
7. To terminate the addition of distances, simply meas-
ure a distance without first pressing the "Plus" but-
ton.
All previous measuring and calculation results are
shown in the intermediate results lines.
8. Press the C-button to clear the display.
7.3 Subtracting distances
-
0.625
Individual distances can be conveniently subtracted from
each other, e.g. in order to determine the distance
between the underside of a pipe and the ceiling. This
can be done by subtracting the distance between the
floor and the underside of the pipe from the distance
between the floor and the ceiling. If the pipe diameter is
subtracted, the result is the distance between the top of
the pipe and the ceiling.
1. Press the "Measure" button (the laser beam
switches on).
