Misreflections
Misreflections can be produced by highly reflective objects. Highly reflective objects are, for
example: windows, stainless steel trim panels or metal pipes. The misreflections are pro-
duced if the measurement beam from the NAV350 is incident perpendicularly on these ob-
jects.
Fig. 16:
Minimum distance from reflectors to other reflecting objects
So that these misreflections are not interpreted as reflectors, it is to be ensured the reflec-
tors fitted are always at least 300 mm (11,81 in) from these objects. If the minimum dis-
tance cannot be maintained for specific objects, these objects are to be covered using a
material with low reflection properties.
Subsequent movement of reflectors
Movement of reflectors that are also still in the measurement area of the NAV350 after they
have been moved, will make the result of the measurement incorrect and must be correct-
ed.
For correction the reflector must be returned to its original position or the coordinates of the
new reflector position must be measured using the M
APPING
function and transferred to the
NAV350 using SOPAS ET.
Subsequent removal or obscuring of reflectors
If reflectors are obscured or removed, the NAV350 continues to determine its position
based on the remaining reflectors without interruption, as long as at least three reflectors
are visible from the position of the scanner head.
