7 Operation

7.1 Distance measurement

NOTE
Generally speaking, the individual steps in all functions
are always assisted by the graphic symbols displayed.
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.
NOTE
After starting a function, the laser beam is already
switched on.
NOTE
You will obtain the most accurate results when all mea-
surements within one function are taken from the same
point of contact and axis of rotation.

7.1.1 Measuring modes

Distances can be measured using two different mea-
suring modes, i.e. single measurement and continuous
measurement. Continuous measurement is used for set-
ting out given distances or lengths and can also be used
where access is difficult, e.g. at corners, edges and in
niches, etc.
7.1.1.1 Single measurements
If the tool is switched off it can be switched on by pressing
the "On/off" button or the "Measure" button. If the tool is
switched on by pressing the "Measure" button the laser
is also activated, so step one described below can be
omitted.
1. Switch on the laser by pressing the "Measure" but-
ton.
2. Aim the tool at the target and press the "Measure"
button.
The measured distance will be shown in the result
line in less than a second.
7.1.1.2 Continuous measuring (tracking)
NOTE
During continuous measuring, distances are updated in
the result line at the rate of approx. 6 - 10 measurements
every second. The measuring rate depends on reflectivity
of the target surface. If the signal tone is active, continu-
ous measuring is indicated by a signal tone approx. 2 - 3
times per second.

7.1.2 Measuring in bright conditions
We recommend use of the PDA 50, PDA 51 or PDA 52
target plate for long distances and in very bright light
conditions.

7.1.3 Measuring range

7.1.3.1 Increased range
The range of the tool is generally increased when mea-
surements are taken in the dark, at dawn or dusk and
when the target and/or the tool is shaded from bright
light.
Use of the PDA 50, PDA 51 or PDA 52 target plate also
increases the range of the tool.
7.1.3.2 Reduced measuring range
Measuring range may be reduced in bright conditions,
e.g. in bright sunlight or when working under very pow-
erful floodlights.
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.
7.2 Adding / subtracting distances
Individual distances can be added or subtracted conve-
niently.
Addition can be used, for example, to determine the total
length of window and door reveals or to add several
part distances together in order to determine the total
distance.
Subtraction can be used, for example, to determine the
distance between the underside of a pipe or duct 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
Press the "Measure" button for about 2 seconds to
activate continuous measuring mode.
Measuring is stopped by pressing the "Measure"
button once again.
The last valid measurement is then shown in the
result line in the display.
