Note that no image will be created for areas of the grid
that are not scanned in both directions.
It is possible to repeat the previous row or column by
pressing
Cancel . This may be necessary if the user is
not sure that the scan field has not been followed accu-
rately. Pressing
Cancel a second time aborts the scan
and returns to the main menu.
This symbol may appear when the scanner is being
moved over the surface. It indicates that the scanner is
being moved too quickly to allow it to process all the
signals generated. The maximum speed is 0.5 m/s or
20 inch/s. If this symbol appears, press
Confirm and
repeat the row or column you were scanning. In all cas-
es, move the scanner more slowly over the surface.
When the scan is complete, press the Confirm button
to return to the main menu. The data may be transferred
to the monitor for viewing and evaluation. Please refer
to section 7.4.
-CAUTION-
Pressing the Cancel button causes the recorded Images-
can to be deleted. The screen then returns to the main
menu.
7.2.7 Blockscan
Blockscan automatically stitches Imagescans together
to give an impression of the reinforcement layout over
a large area. The exact bar position, depth and diame-
ter can also be determined on the monitor by selecting
each Imagescan individually.
Attach the reference grid in the same way as when mak-
ing an Imagescan. Mark the edge(s) for the transition
to the next grid using a PUA 70 marker, as shown below.
Switch on the scanner. Move to the Blockscan symbol.
The battery level is given, together with the number of
Imagescans currently held in the memory out of a max-
imum of 9.
To begin, select Blockscan from the main menu.
A representation of a Blockscan is shown on the screen.
Each square represents an Imagescan. Up to 3
×
3 Image-
scans can be scanned. Select the position of the first
Imagescan that you will make in the series using the
Arrow buttons . Press Confirm to begin the first Image-
scan. Note that the coordinates of any points on the
Blockscan will be referenced from the upper left corner.
Refer to the previous section for details on how to car-
ry out the Imagescan. When the Imagescan is complete,
