Electrical Safety; Description Of The System - Hilti PS 50 Manual De Instrucciones

d) Take care to ensure that the service cover on the
tool is always securely closed. The service cover
may be opened only at a Hilti Service Center.
e) You must check the accuracy of the tool after it
has been dropped or subjected to other mechan-
ical stresses.
f) Although the tool is designed for the tough con-
ditions of jobsite use, as with other measuring
en
instruments it should be treated with care.
g) Although the tool is protected against the entry of
moisture, it should be wiped dry before being put
away in its transport container.
h) Check the accuracy of the tool before using it for
detection or measurement.

4.5 Electrical safety

a) Keep the batteries out of reach of children.

5 Description of the system

5.1 Basic principle 3
The tool scans in direction "A" to the depth indicated in
the display. If an object is located beneath the sensor it
will be shown in the sensor area of the display. Scanning
takes place only while the tool is being moved in direction
"B" and so long as the tool is moved a distance of at least
10 cm (3.9 in). Objects that differ from the surrounding
material will be detected. The display shows the position
of the object, its approximate depth and, when possible,
the object class. Due to the operating principle employed,
the upper edges of objects that lie transversely to the
scanning direction will be reliably detected. In order to
locate objects that lie longitudinally along the path of
the scan it is always necessary to make a second scan,
perpendicular to the path of the first scan.
The tool is equipped with various sensors that allow
object location, depth measurement and material classi-
fication.
When several objects are positioned one above the other
in the material being scanned, the object closest to the
surface will be shown in the display. The image of the
object shown in the display may differ from the actual
characteristics of the object concerned. In particular,
very thin objects will be shown thicker than they actually
are. Large, cylindrical objects (e.g. plastic pipes or water
pipes) shown in the display may appear narrower than
they actually are.
Depending on the size and depth of the object detected,
identification of the object class may also be possible.
5.2 Scanning modes
The tool features the following scanning modes:
Universal
Concrete
Wet concrete

b) Remove the batteries from the tool if it is to remain un-
used for some time. The batteries will self-discharge
and may begin to corrode if stored for a long period.
c) Always replace all batteries at the same time. Use
only batteries of the same capacity and from the
same manufacturer.
d) Do not allow the batteries to overheat and do not
expose them to fire. The batteries may explode or
release toxic substances.
e) Do not charge the batteries.
Do not solder the batteries into the tool.
f)
g) Do not discharge the batteries by short-circuiting.
This may cause them to overheat and present a risk
of personal injury (burns).
h) Do not attempt to open the batteries and do not
subject them to excessive mechanical stress.
4.6 Transport
Always remove the batteries before shipping the tool.
Floor heating
Drywall
Hollow brick
Signal View
The tool can be adapted for use on various materials by
selecting the appropriate scanning mode.
NOTE
Scanning performance depends greatly on selection of
the correct scanning mode. Make sure that the correct
/ optimum scanning mode for the applicable material
is selected as the results may vary depending on the
scanning mode used.
5.2.1 Universal
The "Universal" scanning mode is suitable for use in most
applications on solid masonry or concrete. In this mode,
metal or plastic objects and electric cables are detected.
Cavities in brick or empty plastic pipes with a diameter
of less than 2 cm (0.8 in) will probably not be detected.
The maximum detection depth is 8 cm (3.2 in).
5.2.2 Concrete
The "Concrete" scanning mode particularly suitable for
use on dry steel-reinforced concrete. In this mode, steel
reinforcing bars, plastic or metal pipes and electric cables
are detected. The maximum detection depth is 15 cm
(6 in).
The "Universal" mode should be selected in order to
avoid errors when the tool is used to scan thin concrete
walls.
5.2.3 Wet concrete
The "Wet concrete" scanning mode is particularly suitable
for scanning fresh concrete. In this mode, steel reinfor-
cing bars, plastic or metal pipes and electric cables are
