General Information
The reception lens 17 and the laser beam outlet 16 must not
be covered when taking a measurement.
The measuring tool must not be moved while taking a measure-
ment (with the exception of the continuous measurement
function). Therefore, place the measuring tool, as far as this is
possible, 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.
Influence Effects on the Measuring Range
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 19 (acces-
sory) and the laser target plate 20 (accessory), or shade off the
target surface.
