Interference in images may occur due to:
•
Scraps of reinforcement in the concrete
•
Tie wires where rebars cross
•
Aggregates with ferromagnetic properties
•
Ends of bars lying parallel to the scanning plane
•
Ends of bars lying at right angles to the scanning
plane (standing bars)
Note
Diameters and depths calculated in the area where
interference occurs must be treated with caution
as they may be inaccurate.
Scanning columns and beams for making penetrations
In such cases where the reinforcement must not be damaged, ensure that Imagescans are made on at least
three sides of the component in order to ensure that shear bars (placed at an angle in the concrete) can also
be identified.
Simple diameter check
A simple, rough check of the diameter of the bars in the
first layer can be made by deducting the depth of the
second perpendicular layer from that of the first. This
assumes however that the two layers touch each other
or are at least very close.
5.16.6 PC software
The Hilti PROFIS Detection PC application provides functions for enhanced analysis, easy creation of reports,
data archival, image and data export to other PC applications as well as automated batch processing of
large volumes of data.
Die Hilti PROFIS Detection MAP PC application makes it possible to assemble large volumes of data as a
large-area image or evaluation scan with an area of up to 45x45 m.
Detailed information about using the PC applications can be found in the Help menu.

Possible cause
The maximum scanning speed of
0.5 m/s was exceeded.
The maximum scanning speed of
0.5 m/s was exceeded.
Action to be taken
▶ Press the Confirm button and
repeat the scan. Move the
scanner over the surface more
slowly.
▶ Press the Confirm button.
Repeat the scanning operation
from the starting point or from
the last point at which a marker
was set. Move the scanner over
the surface more slowly.
