Switching the display illumination on and off
The display illumination can be switched on or off with the display illumination
button (6).
Switching audio signal on/off
The audio signal can be switched on/off with the audio signal button (7). When the audio
signal is switched off, the audio signal indicator (a) appears on the display.
How it works (see figure B)
The measuring tool checks the base material of the sensor area (13) in the measurement
direction A up to the maximum detection depth. Objects that are different from the ma-
terial of the wall are detected.
Move the measuring tool in a straight line in direction B over the wall.
Always move the measuring tool over the base material applying light pressure, without
lifting it off or changing the pressure.
During the measurement, the contact pads (12) must always remain in contact with the
surface.
Measuring process
Place the measuring tool on the surface to be examined and move it in direction B.
– When the measuring tool approaches an object, the amplitude in the measuring
indicator (i) increases and the light-up ring (1) lights up yellow.
– The amplitude decreases when the measuring tool moves away from the object.
– Above the centre of an object, the measuring indicator will indicate maximum amp-
litude; the light-up ring (1) will light up red and an audio signal will sound.
For small or deep-lying objects, the light-up ring (1) can continue to light up yellow
without the audio signal sounding.
Wide objects are not indicated by the light-up ring or the audio signal throughout
u
their complete width.
In order to locate an object more precisely, move the measuring tool repeatedly (3×)
back and forth over the object. The fine scale (j) is activated automatically in all operat-
ing modes. The fine scale indicates a full amplitude when the object is below the centre
of the sensor or when the maximum amplitude of the measuring indicator (i) is reached.
In Drywall and Metal operating modes, the object centre indicator CENTER (k) also lights
up.
Wider objects in the base material can be identified by a continuous high amplitude of
the measuring indicator (i) and fine scale (j). The light-up ring (1) will light up yellow.
The duration of the high amplitude corresponds approximately with the object width.
