7.2.5.5 Setting a marker
When recording, the surfaces of many structures con-
tain obstacles that prevent the scan being recorded
without lifting the scanner from the surface. Examples
of such obstacles are piers or columns in a wall, door
openings, expansion joints, corners etc.
If an obstacle is encountered, a marker may be set. This
interrupts the scan and allows the user to safely remove
the scanner from the surface, place it beyond the obstruc-
tion and then continue scanning. It also indicates where
certain objects are located within a scan, providing addi-
tional information for referencing the scan data to the
actual surface.
To set the marker press and hold Confirm, whilst in
recording mode. The diskette symbol will be crossed
out, indicating that recording has been suspended and
a marker has been set.
Then lift the scanner from the surface whilst still hold-
ing the Confirm button depressed. If necessary, mark
the position on the surface using a PUA 70 marker. Place
the scanner back on the surface beyond the obstacle,
release Confirm and continue scanning. The marker will
be shown as a vertical line in the scan data when viewed
on the monitor or in the PC application.

-CAUTION-
De to interruption of the recorded signal, scanning results
are less accurate immediately before and after the point
where a mark is made.
7.2.6 Imagescan
Imagescan is used to create an image of the reinforce-
ment layout. The depth and diameter of the bars can be
determined.
Firstly, a PSA 10 or PSA 11 reference grid has to be fixed
to the wall. Use the adhesive tape supplied. This tape is
designed specifically for sticking to concrete structures
and can be torn off the roll by hand at the correct length.
For most surfaces, a 100 mm (4 inch) piece of tape at
each corner is adequate to secure the grid. Particularly
moist or dusty surfaces may require a length of tape
along each side of the grid.
Alternatively, a grid can be marked directly on the sur-
face. Using a straight edge (such as a piece of wood) as
a guide, mark a 4 × 4 grid with 150 mm spacing between
the parallel lines.
Switch on the scanner. Move to the Imagescan symbol.
The battery level is displayed together with the number
of Imagescans currently held in the memory out of a
maximum of 9.
Select Imagescan from the main menu.
The Imagescan screen is displayed.
A representation of the grid appears on the screen with
a suggested starting point. This is always upper left and
will suffice for most scans. Image data will only be gen-
erated for areas of the grid that have been scanned both
vertically and horizontally. In some cases, obstacles on
the scan area may prevent this (e.g. a pipe penetrating
a beam). The starting point can then be changed to opti-
mize the area scanned in such a case. Use the Arrow
buttons to change the starting point.
