The measurements are taken at the center of the laser beam, even when
the laser is pointed at surfaces diagonally.
In order to get an accurate measurement, the laser measure must not be
moved while taking a measurement. Therefore, place the laser measure,
as much as possible, against or on a firm stop or supporting surface. To
record the current measurement value on the display, press the measuring
button (1) (see also "Measuring Length" on page 14).
Effects to the Measuring Range
The measuring range depends on the light conditions and the reflection
properties of the target surface.
Effects to the Measuring Result
Due to physical effects, faulty measurements cannot be excluded when
measuring on different surfaces which include:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal, glass),
– Porous surfaces (e.g. insulation materials),
– Structured surfaces (e.g., roughcast, natural stone).
Also, air layers with varying temperatures or indirectly received reflections
can affect the measured value.
Accuracy Check of the Distance Measurement
The accuracy of the distance measurement can be checked as follows:
– Select a permanent measuring section with a length of approx. 3 ft to
33 ft (1 m to 10 m); its length must be precisely known (e.g. the width
of a room or a door opening). The measuring distance must be indoors;
the target surface for the measurement must be smooth and reflect well.
– Measure the distance 10 times after another.
The deviation of the individual measurements from the mean value must
not exceed ±1/8" (±3.0mm). Log the measurements, so that you can com-
pare their accuracy at a later point of time.
Operation - Fitting the Adapter
To Attach Adapter (see figure 1): Attach the adapter to the laser measure
so that it clicks into place.
To Remove Adapter: Press the release buttons (9) and take off the adapter.
