3.4 Technical advice
Pay special attention to the following technical advice to avoid
operational problems:
Fix the pad to the surface being investigated with adhesive tape.
Avoid treading on the paper pad, this may damage it making it
unusable.
Block the antenna cable to the handle with Velcro when using
the device so the cable doesn't get in the way
If a high frequency antenna is being used, it must be connected
to the trigger boxand the trigger box to the DAD using the D-D
cable.
The optical detector device isn't waterproof therefore it
shouldn't be used in damp conditions.
When the optical detector is in use, don't look at the laser beam.

The Aladdin field consists of the following parameters: ·
Automatic: an automatic acquisition mode in which once the
other parameters have been set, it is sufficient to press start,
stop and any automatic user markers, positioning the system
just before the horizontal line shown on the pad. This mode
contains automatic data quality control (see the Tolerance
field later on).
Manual: in this mode, once you start, the acquisition is
performed independently of the position of the antenna with
respect to the pad. This mode also contains automatic data
quality control (see the Tolerance field later on).
Manual (no check): this acquisition mode has no type of
automatic data quality control, and leaves you free to acquire
data as you wish. In this case, the system limits itself to
providing an acoustic warning if the system is not following
the pre-established scan path. It is also possible to make
acquisitions without using the optical reader.
Auto marker: this sets an automatic user marker each time
the antenna crosses a horizontal line on the pad
Carpet grid: this represents the size of each square that the
optical detector signals with user markers on the pad; e.g.
2cm represents a 2x2cm square, while 4cm represents a
4x4cm square and so on.
Acquisition:
Length: this represents the length of the pass you intend
to perform on the pad..
Total scans: this represents the total number of passes
that you intend to perform starting from the initial
coordinate indicated on the pad.
Start coordinate: this represents the initial acquisition
coordinate shown on the pad..
Tolerance (% sweep out): this is the factor that controls
the quality of acquired data; this factor controls how
much road is covered by the antenna with respect to the
pre-set value and if the path length is greater than your
user set percentage error. In Automatic mode, if this value

is exceeded, the software forces you to repeat the pass
being performed.
You also have the option of calling up the virtual keyboard by pressing
the button shown in Fig. 4-3.
To confirm all the set parameters, press the OK button in the window
shown in Fig. 4-3.
Confirmation that Aladdin has been activated is given in the initial K2
SW window, with ALADDIN shown under the other lights (circled in
Fig. 4-6 in red) accompanied with three of its own lights which
simulate the three infrared sensors that make up the optical reader.

4.2 Work procedure using the Aladdin system
4.2.1 "Automatic" mode
Step 1: Assemble the system (see Fig. 4-7), and place the pad on the
surface to be investigated (Fig. 4-8).

NO TE! The pad consists of a grid of longitudinal and transversal lines
that indicate the profiles to be traced using the antenna. In
addition, there is a black square at the bottom right hand corner
which represents the antenna
parking area, containing an optical
detector that temporarily deactivates the acoustic signal.
Step 2: Start the K2 SW, perform the calibration (as described in Par.
4.2 and 4.3 of MN_2004_005) and set the Aladdin structures kit
parameters (as described in Par. 4.1 of this manual).
NO TE! If you are using a bipolar antenna, only longitudinal scans must
be performed; for a single high frequency antenna, perform both
longitudinal and transversal scans

Step 3: Position the antenna on the initial preset coordinate (Fig. 4-9)
in the L (or T) direction and carefully position the antenna until the
acoustic signal stops
Fig. 4-9 – Starting position
Step 4A (Standard System): Press one of the START buttons placed
on the handle or directly on the antenna (Fig. 4-10); a special acoustic
signal will confirm that the START button has been pressed
Step 4B (US System): Press one of the START buttons placed on the
handle or directly on the antenna and keep it pressed (Fig. 4-10); a
special acoustic signal will confirm that the START button has been
pressed. Releasing the button, will stop the collection after 10 sec.

Fig. 4-10 – START buttons
Step 5: Move the antenna in the pre-established direction; acquisition
will start as soon as the optical detector crosses the first horizontal
line.
Step 6: If you have pre-set "Auto Marker", each time the antenna
crosses a horizontal line, the system will insert a User Marker on the
scan.
Step 7: The scan will be automatically STOPPED as soon as the
optical detector encounters the last horizontal line pre-set by the
operator on the basis of the set scan Length.
Step 8: Continue the procedure described from step 3 onwards on the
next pre-set coordinate.
WARNI NG!
There is one particular case where you must pay attention:
if you use a 2x2 pad, the optical detector must carefully
follow a thick line f
ollowed by a fine line, the fine lines
being indicated with the extension F (see for example Fig.
4-11 which shows increasing coordinates (e.g. 1, 1F, 2, 2F
and so on). In Automatic
mode, you have to keep alignment
under control during scanning, making use
of the laser
pointer.

Fig. 4-11 – Sequence of 2 scans using a 2x2 pad
4.2.2 “Manual” Mode
Steps 1-4: Follow the same procedure described for "Automatic"
mode above.
Step 5: Acquis ition starts when you press the START button,
independently of the position of the first horizontal line encountered.
Step 6A (Standard System): Insertion of User Markers during
scanning is performed by rapidly pressing the START button.
Step 6B (US System): Insertion of User Markers during scanning is
performed by rapidly releasing and pressing again the START
button.
Step 7A (Standard System): The scan is STOPPED by keeping the
START button pressed
Step 7B (US System): The scan is STOPPED by releasing the START
button
NO TE!
The system keeps control of data quality (Tolerance
) in both
Automatic and Manual mode. In fact, if this tolerance is
respected, a confirmation acoustic signal is activated; if the
tolerance exceeds the pre-
set percentage during the scan,
an error acoustic signal is heard, the scan isn't saved and you
have to repeat it.

Step 1-7: In this case the user must use the PSG carpet –Pad Survey
Guide Guide (Fig. 4-12) with the slide applied under the frame (see
Par. 3.2.3).
Fig. 4-12 – PSG Carpet
The PSG carpet holds alternated upper and lower guides in order to
make the slide perfectly fit and for the antenna to realize straight
scans. Also the slide holds a special film on its external surface
removing to the minimum the friction during the drag of the antenna
on PSG. Finally the PSG holds on its edge a graduated horizontal pole
with the indication of numbers and letters in progressive sequence, in
order to give to the user a reference point at the beginning of the scan
(Fig. 4-13).

Follow the same operative procedure used in the "Manual" procedure
described above.
NOTE!
The main difference with respect to the "Manual" mode consists
in the absence of the Tolerance control factor, therefore you are
free to choose how long the scan should be (Length). This mode
is useful when scan
s of different lengths have to
be performed. This is the only mode in which the user can work
with the optical detector deactivated.
WARNI NG!
Once the scans are finished, you can activate the
Review Acquisition
button (see Par. 4.7 in manual
MN_2004_005); this opens the window shown in Fig. 4-
12, from where pressing the Gred3D button (circled in red),
you can automatically start the GRED 3D NAVIGATOR
SW for the survey underway. The GRED 3D
NAVIGATOR SW can be used to process the raw data as
required.
For information on the GRED 3D NAVIGATOR
SW, see the user manual MN_2005_002.
