1. Safety / care and maintenance
Safety precautions Ferroscan System Safety precautions TCU12 H
Important: The following safety precautions must be
observed
● The mains supply must correspond to the information printed
on the rating plate. 230 volt units may also be connected to a
220 volt supply.
● Only Hilti RB10 batteries should be charged using this charger.
The TCU12H charger and RB10 battery have been designed to
work together optimally.
● The charger must be able to give off heat during the charging procedure. Please ensure that the ventilation slits are not
obstructed.
Do not use the charger in closed containers!
● Do not short circuit the contacts.
● The charger should be located in a dry, clean and cool place
but protected from frost.
As this unit is connected to the mains supply, safety precautions
must be observed.
Care and maintenance
Always disconnect the mains plug from the mains supply before
cleaning or servicing the TCU12 H. The contacts in the battery
compartment must be kept clean (free of oil and grease).
The ventilation slits must be free of dirt and dust.
A damaged supply cord must be replaced by a Hilti repair centre, as special tools are required for carrying out the repair correctly.
Safety precautions RB1O
Important: The enclosed safety precautions must be
observed
● Before operating the unit, check that the RB10 battery has
been fitted securely.
● Do not continue to operate the unit until the RB 10 battery
becomes totally exhausted (unit completely inoperative). The
battery cells may suffer damage if completely discharged.
● The BP 10 battery should be stored in a dry place and protected from frost. Heat sources such as direct sunlight or radiators should be avoided.
● The RB10 battery should be used only in the units indicated
by Hilti. Use only the charger specified by Hilti for charging the
RB10 battery.The charger,battery and other units of the system
are designed to work together optimally.
● If necessary, clean the RB10 battery terminals before inserting it into the charger or into the unit.
● Do not short circuit the RB10 battery terminals.
● New RB 10 batteries or batteries which have not been used
for a long period only reach full capacity after several
charge/discharge cycles.
Care and maintenance
Battery terminals must be kept clean (free of oil and grease). If,
after having been subjected to considerable use, battery capacity drops below an acceptable level, we recommend that the
battery is checked by Hilti.
Important: RB10 batteries which have reached the end of their
life should be returned to Hilti for recycling.
Important: The following safety precautions must be
observed
● A qualified technical expert (e.g. civil engineer) must be
consulted when making use of the measurement data for
safety relevant purposes (e.g. structural design).
Care and maintenance
The Ferroscan FS10 system is a testing instrument. Although it
has been designed for arduous jobsite conditions (impact and
vibration resistance) it should be treated with the appropriate
care.
The LCD display is suitable for operation in temperatures within
the range –10°C
% to % +50°C. Extreme temperatures resulting from exposure to direct sunlight for long periods and other
sources of heat such as radiators should be avoided!
The PC and printer connections should always be covered when
not in use in order to protect the instrument from the effects of
dust and water spray.
The RS10 scanner required to be recalibrated after a period of
use of approx. two years. It is recommended that the RS10
scanner is returned to the nearest Hilti centre for recalibration
after a period of two years. If the measurement characteristics
lie outside tolerance limits, the complete system becomes inoperative. No further readings can be taken.
The lithium auxiliary battery has a life of approx. six years. It is
recommended that this battery is checked at the two-yearly calibration intervals.

screws with plastic anchors.
Charging functions
➀ Charger ready LED (green)
The charger ready LED (green) lights continuously when the charger is connected to the
mains supply.
➁ Charging indicator LED (red)
The charging indicator LED (red) lights continously when the RB10 battery is being
charged. The charging indicator LED (red)
blinks (20.5 sec. off, 1 sec. on) after the charger has switched to trickle charge mode.
➂ Battery compartment
In order to ensure correct contact, the RB10
battery engages with a “click” in the battery
compartment. This feature is particularly important when the charger is mounted on a wall.
➃ Wall mounting
Make use of the holes provided on the base of
the charger housing for wall mounting.
Notes on charging procedure
If charging does not begin immediately after
inserting the RB10 battery into the charger,
then the battery is either too cold or too warm.
The battery can remain in the charger. The
charging procedure begins automatically after
the RB10 battery has reached the specified
temperature (0°–45°C). The charger is equipped with an electronic temperature-monitoring
device. Under normal conditions,the RB10 battery is charged after approx. one hour, after
which a trickle charge current counteracts the

Note: As a result of the detection principle utilised, reinforcement which runs parallel to the direction of movement of the
scanner cannot be detected. The grid area must be scanned in
two directions, at right angles to each other.
Note: In order to receive a correct image, it is necessary to follow the prescribed scanning traces in the prescribed sequence.
A) Attach the supplied paper reference grid, using adhesive tape,
to the surface of the concrete. Alternatively, if the condition of the
surface does not allow the use of adhesive tape, the grid can be
marked directly on the concrete using the ruler. Mark out trace
numbers one to eight.
Optimum results will be achieved when the grid axis lies parallel to the reinforcement.
B) Connect the RS10 scanner to the RV10 monitor using the
RC10 connecting cable. Press the button. Press the
key.The starting position of the scanner is shown on the screen
in black.

in vertical and horizontal directions.
Start
Marks are printed on the papier reference grid as an aid to positioning the scanner. If the reference grid is marked directly on
the concrete surface using the ruler, the scanner must be positioned according to the effective scanning width represented by
the grid. Guide the scanner along the trace lines. The distance
covered is displayed on the screen. When the 600 mm trace has
been fully scanned, an acoustic signal is given automatically.
The scan can be interrupted before reaching the end of the 600
mm trace (e.g. because of an obstruction). In this case, the
start/stop button on the scanner or the key on the monitor
must be pressed. The scanned trace is displayed on the monitor
as a shaded area. On the screen, the starting position for the
scanner moves automatically to the next trace.

using the cursor keys ( ) situated at bottom right
of the screen. The coordinates of the cursor, or respectively, the
reinforcement, are displayed on the right at the bottom of the
screen.
Press the function key. Depth of coverage and diameter (∅) are displayed on the left at the bottom of the screen.
Note: The diameter (∅) is displayed if and only if a reliable read-
ing is allowed for by the detection signals i.e. if the distance
between rebars corresponds to min. twice the coverage and the
reinforcement is not too close to the edge of the image. This
information can be obtained at a depth of coverage of up to 60
mm.

5.3 Determination of position, depth of coverage and diameter of reinforcement
The unit of the display diameter depends on the scanner used
for the measurement. If the scanner is calibrated for standard
diameters according to american ACI standard (see section 7),
the diameter is shown in standard number #. Otherwise it is displayed in “mm”.
The coordinates of the cursor and the coverage (depth) are in
general displayed in “mm”. If the option “Display” (Engl.: in.) is
chosen (see section 5.1), they will be shown in “in”.
Due to the lack of space available, the units “in.” or “mm” are
not explicitly displayed. The coordinates and the depth in “mm”
are shown in integers. In “in.” they are displayed with a deci-
mal point.

The RV10 monitor can store up to 42 images in its memory.
When the monitor is switched on, the last recorded image
appears on the screen automatically. Each image is identified at
the top of the screen by a consecutive number and date/time of
scanning. The number of images in the system's memory is displayed at the foot of the screen.
Two types of image are possible. A picture image records all
data for the reinforcing bars within the area of the scan. This
enables position, depth and diameter to be determined subsequently.A quickscan image records the length of the scan, position and number of bars as well as depth of coverage over the
bars that lie at right angles to the direction of the scan.
Press the cursor keys in order to recall a particular
image.
When the image to be printed appears on the screen:
