The calibration symbol appears in the status bar to the
left of the display. If the information entered was accu-
rate, the depth and diameter around the point will be
shown with increased accuracy.
-WARNING-
Calibrating the scan with incorrect values can lead to depth
readings outside the quoted accuracy specifications.
7.3.6 Blockscans
Blockscans consist of up to 3
×
3 Imagescans that have
been scanned at positions adjacent to one another and
then automatically stitched together.

7.3.6.1 Analyzing a Blockscan
Select Analyze.
View Range + and View Range – raises and lowers the
depth at which the scan is viewed, as with Imagescan.
This is useful when trying to find which bars lie closest
to the surface and for an overall impression of how lev-
el the reinforcement is compared to the concrete sur-
face.
Use the arrow buttons to select the block you wish to
analyze.
Select Scan displays the Imagescan marked for
analysis. Refer to section 7.3.5 for details of how to ana-
lyze individual Imagescans.
7.3.7 Quickscans
Quickscans recorded in the scanner can be analyzed to
provide information about the number and average depth
of reinforcing bars over a large area of the structure.
The Quickscan is displayed as a graph containing a series
of vertical bars or peaks. The horizontal axis represents
the distance traveled along the structure. The vertical
axis represents the signal strength or, after analysis, the
depth of cover. Each peak represents a reinforcing bar.
Select Analyze … to analyze the Quickscan.
-NOTE-
To carry out an accurate analysis, the diameter of the
bars must be known and entered. If the bar diameter
has been set in the scanner, this diameter will be trans-
ferred automatically to the monitor. If the diameter has
