7.3.5 Imagescans
Imagescans show a representation of the reinforcement
layout. The layout can be referenced on the surface, the
depth determined at any point and the diameter of a bar
estimated at any point.
Select Analyze … to analyze the image.
7.3.5.1 Analyzing the image
The bar depth and diameter may be determined at any
point on the image. Other analysis options include view-
ing horizontal slices through the image at different depths
and a calibration option for an accurate check of depth
of cover.
View Range + and View Range – raise or lower the
depth at which the scan is viewed. This is useful when
trying to find which bars lie closest to the surface and
for an overall impression of how level the reinforcement
is compared to the concrete surface.
Full Scan Analysis
This function performs an analysis of the complete image.
All bars within the area of the image are calculated and
shown.
Cal. Depth/Ø – Used to calculate the depth and diame-
ter of a bar at the point where the cursor lies.
-WARNING-
When scanning bars that are welded, it must be expect-
ed that accuracy will not be within specifications. It is
not possible to determine from the image whether bars
are welded at their intersection points. If in doubt, remove
concrete from the structure at an intersection to deter-
mine whether the reinforcement is welded.
7.3.5.1.1 Selecting the view range
Press View Range to reduce the image depth viewed.
The current depth range viewed is displayed in the infor-
mation bar at the bottom of the screen (e.g. 0–85 mm).
Use View Range – and View Range + to adjust the depth
at which the image is viewed. In this way it is possible
to determine which bars lie closest to the surface and
how level the reinforcement is in relation to the surface.
In the example shown, the vertical bars lie closest to the
surface.
