Before drilling, sawing or routing into walls, refer to other sources of informa-
u
tion to ensure that you eliminate hazards. As the measuring results can be influ-
enced through ambient conditions or the nature of the wall, there may be a hazard
even though no object is displayed in the information area, no audio signal sounds and
the light-up ring (4) lights up green.
Operating Modes
When detecting, you can choose between three operating modes and can activate two
modes simultaneously.
<Wood> operating mode (see figure B)
<Wood> operating mode is designed for finding wooden beams in dry walls.
When the measuring tool is placed on the wall, the light-up ring (4) lights up yellow until
the signal can be clearly assigned by moving the measuring tool around.
Please note that when selecting this operating mode, all objects located in dry walls will
be displayed. You can only rule out the presence of a metal object or electricity cable by
combining this operating mode with the other two operating modes.
This operating mode will also find plastic pipes, especially those that are filled with wa-
ter. Before drilling, sawing or milling, check to ensure that the object found is actually a
wooden beam and not a plastic pipe.
Only use <Wood> operating mode on dry walls.
<Metal> operating mode (see figure C)
<Metal> operating mode is designed solely for finding objects made of metal (e.g. cop-
per pipes or reinforcing steel), regardless of the nature of the wall.
In this operating mode, live cables are not displayed as power cables. In order to find
power cables, you can also select the <Metal> and <Current> operating modes at the
same time.
<Current> operating mode (see figure D)
<Current> operating mode is designed solely for finding single-phase live cables
(110−240 V, 50−60 Hz).
Preparing to take measurements and features of the measuring process:
– The cable must be live. You should therefore connect electricity consumers (e.g.
lights, appliances) to the electricity cable you are trying to find. Switch on the electri-
city consumers to ensure that the electricity cable is live.
– The 50–60 Hz signal from the electricity cable must be able to reach the measur-
ing tool. If the cable is in damp walls (e.g. > 50 % humidity), behind metallic foil (e.g.
