Ends of bars lying at right angles to the scanning
plane (standing bars)
NOTE
Diameters and depths calculated in the area where inter-
ference occurs must be treated with caution as they may
en
be inaccurate.

In cases where the reinforcement must not be damaged,
ensure that Imagescans are made on at least three sides

8 Care and maintenance

8.1 Cleaning and drying

CAUTION
Do not use liquids other than alcohol or water. Other
liquids may damage plastic parts.
Clean the parts of the tool only with a clean, soft cloth.
Moisten the cloth with pure alcohol or a little water if
necessary.
8.2 Storage
Do not store the tool when it is wet.
Dry and clean the tool, its case and accessories before
storing.
Remove the batteries before storing.
After storing for a long period of time, carry out a mea-
surement check before use.
Observe the temperature limits when storing your equip-
ment. This is particularly important in winter / summer if
the equipment is kept inside a motor vehicle (-25°C to
+60°C / -13°F to +140°F).
8.3 Transport
DANGER
Remove the battery before storing or transporting the
tool.
Always use the original Hilti toolbox when transporting
the tool.
28
of the component in order to ensure that shear bars
(placed at an angle in the concrete) can also be detected.
Simple diameter check
A simple, rough check of the diameter of the bars in the
first layer can be made by deducting the depth of the
second perpendicular layer from that of the first. This
assumes however that the two layers touch each other
or are at least very close.
7.6 PC software
The Hilti PROFIS Ferroscan PC application provides func-
tions for enhanced analysis, easy creation of reports, data
archival, image and data export to other PC applications
as well as automated batch processing of large volumes
of data.
The Hilti PROFIS Ferroscan MAP application makes it
possible to merge large volumes of data, allowing the
creation and evaluation of large-area images covering
areas of up to 45 x 45 m (148 x 148 ft).
Installation instructions can be found on the Hilti PROFIS
Ferroscan software CD-ROM. Detailed information about
using the PC application can be found in the Help menu.
8.4 Removing / replacing the scanner wheels
CAUTION
Do not overtighten the screw when refitting the wheel as
this may result in damage to the wheel and axle. Replace
only one wheel at a time.
The scanner wheels can be removed either for cleaning
or replacement.
Use a 2.5 mm (¹⁄₈") Allen wrench to loosen and remove
the screw at the wheel axle.
Carefully pull the wheel off the axle while holding the op-
posite end of the axle or other wheel. If necessary, clean
the casing and/or wheel carefully see 8.1 before refitting
the wheel to the axle and reinserting and tightening the
screw.

8.5 Hilti Calibration Service

We recommend that the tool is checked by the Hilti
Calibration Service at regular intervals in order to ver-
ify its reliability in accordance with standards and legal
requirements.
Use can be made of the Hilti Calibration Service at any
time, but checking at least once a year is recommended.
The Calibration Service provides confirmation that the
tool is in conformance, on the day it is tested, with the
specifications given in the operating instructions.
After checking, a calibration sticker applied to the tool and
a calibration certificate provide written verification that the
