7.6.4 Measuring wall thickness
Determining the thickness of walls, ceilings or floors.
7.7 Measurements to check accuracy 9
NOTE
Check the accuracy of the tool before making important
measurements or if the instrument has been dropped.
en
NOTE
Do not measure in corners or immediately adjacent to
concrete walls containing steel reinforcement. In order to
avoid influence by metal objects, it is recommended that
the actual measurements are made at points offset from
the reference point by a defined distance (for example,
200 mm / 8 in).

8 Care and maintenance

8.1 Cleaning and drying

Use only a clean, soft cloth for cleaning. If necessary,
moisten the cloth slightly with pure alcohol or a little
water.
NOTE
Do not use any other liquids as these may damage the
plastic components.
8.2 Storage
Unpack the tool if it has become wet. The tool, its carrying
case and accessories should be cleaned and dried (at
maximum 40°C). Repack the equipment only once it is
completely dry.
Check the accuracy of the equipment before it is used
after a long period of storage or transportation.
Remove the batteries from the tool before storing it for a
long period.
NOTE
- Leaking batteries may damage the tool.
- Observe the temperature limits when storing your
equipment, especially in winter / summer if the equip-
ment is kept inside a motor vehicle (-25°C to +70°C;
-13 °F to +158 °F).

8.3 Transport

Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
CAUTION
Always remove the batteries before shipping the tool.

8.4 Hilti calibration service

We recommend that the tool is checked by the Hilti cal-
ibration service at regular intervals in order to verify its
reliability in accordance with standards and legal require-
ments.
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 checked, 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
tool is operating in accordance with the manufacturer's
specification.
Calibration certificates are always required by companies
certified according to ISO 900x.
Your local Hilti Center or representative will be pleased
to provide further information.
Possible cause
The transmitter has switched off auto-
matically after 17 minutes.
The PX 10T transmitter battery is
dead.
The maximum measuring range has
been exceeded.
Choose a wall with a thickness of approx. 50 cm
(1.64 ft) that is known to contain no reinforcement
and with surfaces that are known to be parallel.
Check that the PX 10T is secured in position and
then use the receiver to make measurements from
four sides (from above, below, right, left). Mark the
points found and then determine the geometrical
center.
NOTE Calibration at a Hilti service center is neces-
sary if a deviation of more than 6 mm (0.24 in) is
found.
If you doubt whether the surfaces of the wall are
parallel, swap the positions of the transmitter and
receiver on each side of the wall and repeat the
steps described previously. Set up the transmitter
on the previously determined geometrical center. If
the second geometrical center does not coincide
with the original reference point, then the surfaces
of the wall are not parallel.
Remedy
Switch on the transmitter.
Change the battery.
Make the measurements where the
wall is less thick and then measure
the offset to the drilling position.
