If, after having completed this measurement, you want to start a new measuring pro-
cess on another wall, briefly press the Drywall operating mode button (11) in order to
reset the measuring tool.
– In rare cases, the measuring tool is not able to detect the base material because the
sensor area (13) on the rear side is dirty. Clean the measuring tool with a soft, dry
cloth and re-start the measuring process.
Metal operating mode
Metal operating mode is particularly suited to detecting magnetic and non-magnetic ob-
jects, regardless of the nature of the wall.
To activate Metal operating mode, press the Metal operating mode button (10). The
light-up ring (1) and the operating mode indicator (4) above the Metal operating mode
button will light up green.
If the measuring tool passes over a metal object (the light-up ring (1) will light up red),
the type of metal will be shown in the display. For magnetic metals (e.g. iron) the Mag-
netic metal indicator (e) will appear, for non-magnetic metals (e.g. copper) the Non-
magnetic metal indicator (d) will appear.
Note: For reinforcement steel mesh and reinforcements in the examined based material,
an amplitude is indicated over the entire surface in the measuring indicator (i). For rein-
forcement steel mesh, it is typical that the magnetic metal indicator (e) appears directly
above the iron rods, whereas the non-magnetic metal indicator (d) will appear between
the iron rods.
Power cable operating mode
Power cable operating mode is only suitable for detecting live wires (110−230 V).
To activate Power cable operating mode, press the Power cable operating mode
button (9). The light-up ring (1) and the operating mode indicator (4) above the Power
cable operating mode button will light up green.
When a live wire is detected, the indicator for live wires (f) will appear on the display.
Move the measuring tool over the surface again in order to locate the live wire more pre-
cisely. After moving the measuring tool over the surface multiple times, the live wire can
be detected very precisely. If the measuring tool is very close to the wire, the light-up
ring (1) will flash red and the audio signal will sound at a faster rate.
Notes:
– Live wires are detected in every operating mode.
– Live wires can be detected more easily when power consumers (e.g. lamps, appli-
ances) are connected to the wire being sought and switched on. Switch off electricity
consumers before drilling, sawing or milling into the wall.
