Press the Confirm button on the scanner to begin data
transfer. The following may be observed while data trans-
fer is in progress:
The green LED on the adapter blinks rapidly to indicate
that data transfer is in progress. The red LED on the
scanner blinks continuously.
Data transfer takes between 1 and 15 seconds, depend-
ing on the number and length of scans contained in the
scanner. The LED on the adapter lights green again when
data transfer is finished.
This screen is displayed by the scanner when data trans-
fer is complete.
All scan data has then been successfully transferred.
Press the Confirm button on the scanner to delete the
data in the scanner and return to the main menu.
7.4.3 Transferring data from the adapter to the
computer 4
NOTE
To ensure data security, data integrity and to avoid mal-
functions, use only the PUA 95 Micro USB cable supplied
by Hilti.
The PUA 95 Micro USB data cable is used to transfer
data from the adapter to the computer.
The adapter can be removed once data transfer is com-
plete.
NOTE
In order to remove the PSA 55 adapter safely, we rec-
ommend use of the "Remove hardware safely" function
of the operating system. This helps prevent loss of data
integrity.
7.4.4 Transferring data from the monitor to the
computer 4
NOTE
To ensure data security, data integrity and to avoid mal-
functions, use only the PSA 92 Micro USB cable supplied
by Hilti.
The PSA 92 USB data cable is used to transfer data from
the monitor to the computer.
7.5 Tips for scanning and evaluation
The object is too narrow to scan or reinforcement is
too close to an outside edge to be scanned properly.
Use a thin sheet of non-metallic material (e.g cardboard,
wood, polystyrene foam,...) as an overlay that extends
beyond the edge. The scanner can then be moved over
the sheet to beyond the edge of the structure. Note that
the thickness of the board must be deducted from any
depth measurements. The thickness of the board can
be entered in the PC application. This value will then be
automatically deducted from any depth measurements.
The surface is rough.
Rough surfaces (e.g. concrete surfaces with exposed
aggregates) cause additional noise in the signal and may
mean that the depth or diameter of a bar cannot be
determined. In such cases it is also advantageous to
scan through a thin overlay board. Also in this case, the
thickness of the board must be deducted from any depth
measurements.
Interference in images
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
