Operation
Accurate measurements to prisms should be made in Precise+ mode.
•
• Measurements to strongly reflecting targets such as traffic lights in Prism
mode without a prism should be avoided. The measured distances may be
wrong or inaccurate.
When a distance measurement is triggered, the EDM measures to the
•
object which is in the beam path at that moment. If for example people,
cars, animals, or swaying branches cross the laser beam while a measure-
ment is being taken, a fraction of the laser beam is reflected from these
objects and may lead to incorrect distance values.
• Measurements to prisms are only critical if an object crosses the measuring
beam at a distance of 0 to 30 m and the distance to be measured is more
than 300 m.
In practice, because the measuring time is very short, the user can always
•
find a way of avoiding unwanted objects from interfering in the beam path.
WARNING
Due to laser safety regulations and measuring accuracy, using the Long Range
Reflectorless EDM is only allowed to prisms that are more than 1000m (3300ft)
away.
Prism (>4.0km) mode enables distance measurements of over 4.0 km to
•
standard prisms using the visible red laser beam.
The visible red laser beam can also be used to measure to reflective foils.
•
To guarantee the accuracy the red laser beam must be perpendicular to
the reflector tape and it must be well adjusted.
Make sure the additive constant belongs to the selected target (reflector).
