Working Advice - Berner DETECTOR-1 Notice Originale

– When starting a new measuring procedure after-
wards and positioning the measuring tool onto a
different wall or surface, you must briefly press
button 10.
– In rare cases, the measuring tool may not be
able to detect the base material because the
side with the sensor area 12 and the type plate
13 is soiled or dirty. Clean the measuring tool
with a dry, soft cloth and restart the measuring
procedure.
Metal
The operating mode "Metal" is suitable for detect-
ing magnetic and non-magnetic objects independ-
ent of the wall material.
Press button 9 to activate the operating mode
"Metal". The illuminated ring 1 and indication 4
above button 9 light up green.
When the detected metal object is of magnetic
metal (e.g. iron), the symbol e is indicated on dis-
play 3. For non-magnetic metals, the symbol d is in-
dicated. In order to differentiate between metal
types, the measuring tool must be positioned
above the detected metal object (ring 1 is lit red).
Note: For reinforcement steel mesh and steel in the
examined base material, an amplitude is indicated
over the complete surface of measuring indicator i.
For reinforcement steel mesh, it is typical that the
symbol e for magnetic metal is indicated on the dis-
play directly above the iron rods, whereas between
the iron rods, the symbol d for non-magnetic metal
will appear.
Power Cable
The operating mode "Power cable" is suitable only
for detecting "live" conductors (110 – 230 V).
Press button 8 to activate the operating mode
"Power cable". The illuminated ring 1 and indica-
tion 4 above button 8 light up green.
When a "live" conductor is detected, indication f
appears on the display 3. Move the measuring tool
repeatedly over the area to localise the "live" con-
ductor more precisely. After moving over the "live"
conductor several times, it can be indicated very
accurately. When the measuring tool is very close
to the conductor, the illuminated ring 1 flashes red
and the audio signal beeps swiftly.
Notes:
– "Live" conductors are indicated in any operating
mode.
– "Live" conductors can be detected easier when
power consumers (e.g. lamps, machines) are
connected to the sought conductor and
switched on.
– Under certain conditions (such as below metal
surfaces or behind surfaces with high water
content), "live" conductors cannot be securely
detected. The signal strength of a "live" conduc-
tor depends on the position of the cable. There-
fore, apply further measurements in close prox-
14 | English
imity or use other information sources to check
if a "live" conductor exists.
– Voltage-free conductors can be detected as met-
al objects in the operation mode "Metal". This
does not apply for stranded conductors (contra-
ry to solid conductors or cable).
– Static electricity can lead to inaccurate indica-
tion of electric lines, e.g., over a large range. To
improve the indication, place your free hand flat
on the wall next to the measuring tool, in order to
remove the static electricity.

Working Advice

 Measuring values can be impaired through
certain ambient conditions. These include,
e.g., the proximity of other equipment that
produce strong magnetic or electromagnetic
fields, moisture, metallic building materials,
foil-laminated insulation materials or conduc-
tive wallpaper or tiles. Therefore, please also
observe other information sources (e.g. con-
struction plans) before drilling, sawing or routing
into walls, ceilings or floors.
Marking Objects
If required, detected objects can be marked. Per-
form a measurement as usual. Once you have
found the boundaries or the centre of an object,
mark the sought location through the marking
hole 2.
Temperature Control
The measuring tool is equipped with a temperature
control indicator, as accurate measurements are
only possible as long as the temperature within the
measuring tool remains constant.
When the temperature control indicator g lights up,
the measuring tool is not within the operating tem-
perature range or was subject to large variations in
temperature. Switch the measuring tool off and
allow it to adjust to the ambient temperature be-
fore switching it on again.
Warning Function
When indicator b lights up on display 3 and indica-
tion 4 flashes above button 10, the measurement
must be restarted. Remove the measuring tool
from the wall and place it on the base material at a
different location.
When indicator b flashes on display 3, send the
measuring tool in the provided protective pouch to
an authorised customer services agent.
