2 Description

2.1 Use of the product as directed
The tool is designed for measuring distances, adding and subtracting distances and offers many practical functions
such as a timer, area and volume measurement, min/max calculation, setting out, trapezoidal area or painter's area
measurement, Pythagoras function and data memory.
The tool is not designed for leveling.
When using the tool, the safety instructions (section 5) must be observed.
2.2 Display
The display is divided into various areas. The dark, upper area shows information about the status of the range
meter (e.g. measuring reference point, battery status, laser on, laser on permanently). Directly below this area are the
measuring functions (e.g. plus, minus), which can be selected by using the arrow buttons.
When the tool is in measuring mode, the measurements taken are shown at the bottom of the display area (the
result line). When using functions such as "Area", measured distances are shown on the intermediate result line and
calculated results are shown on the result line.
2.3 Display illumination
In low light conditions, the display is illuminated automatically as soon as a button is pressed. The display illumination
intensity is reduced to 50% after 10 seconds. If no button is pressed over a period of 20 seconds, the display
illumination switches off automatically.
NOTE
Illumination of the display consumes additional battery power. Shorter battery life is therefore to be expected when
this feature is used frequently.
2.4 Basic principle
The distance is measured along a laser beam emitted by the tool to the point at which the beam strikes a reflective
surface. The target from which the measurement is taken is clearly identified by the red laser measuring spot. The
range of the tool depends on the reflectance and structure of the target surface from which measurements are taken.
2.5 Taking measurements to rough surfaces
When measuring to a rough surface, e.g. rough plaster etc., an average distance value is measured with the center of
the laser spot weighted higher than the edges of the laser spot.
2.6 Taking measurements to curved or inclined surfaces
If the laser beam strikes the target surface at a very narrow angle, the light reflected may be inadequate. Conversely,
too much light may be reflected toward the tool in situations where the laser beam strikes the target perpendicularly.
We recommend use of the PDA 50, PDA 51 or PDA 52 target plate in both of these situations.
2.7 Taking measurements to wet or shiny surfaces
As long as the range meter can be aimed directly at the surface, the distance to the target will be reliably measured.
With highly reflective surfaces, a reduction in range must be expected and the distance to the actual point of reflection
may be measured.
2.8 Taking measurements to transparent surfaces
It is generally possible to measure distances to transparent or semi-transparent materials, e.g. liquids, polystyrene
foam, etc. Light penetrates these materials, however, and measuring errors may therefore occur. Measuring errors
may also occur when measurements are taken through glass or if objects are present within the line of the laser beam.
