Operating Modes - Bosch GMS 120 Professional Notice Originale

enced through ambient conditions or the nature of the wall, there may be a hazard
even though the measuring indicator (i) does not indicate an object in the sensor
area, no audio signal sounds and the light-up ring (1) lights up green.

Operating Modes

You can achieve the best possible measuring results by selecting the correct operating
mode. You can achieve the maximum detection depth for metal objects in the Metal op-
erating mode. You can achieve the maximum detection depth for live wires in the Power
cable operating mode.
The selected operating mode is always shown by the green operating mode
indicator (4).
Drywall operating mode
Drywall operating mode is designed for detecting wooden and metal objects in dry walls.
To activate Drywall operating mode, press the Drywall operating mode button (11). The
operating mode indicator (4) above the Drywall operating mode button will light up
green.
As soon the measuring tool is positioned on the surface to be examined, the light-up
ring (1) will light up green, indicating readiness to measure.
In Drywall operating mode, all available objects will be detected and displayed:
(c) Non-metallic, e.g. wooden beams
(d) Non-magnetic, but metal, e.g. copper pipe
(e) Magnetic, e.g. reinforcing steel
(f) Live, e.g. power lines
Note: In the Drywall operating mode, other objects, e.g.water-filled plastic pipes, will be
also displayed in addition to wooden and metal objects and live wires. For these objects,
the Non-metallic object indicator (c) will appear in the display.
Nails and screws in the base material may result in wooden beams being identified as
metal objects.
If the display indicates a continuously high amplitude of the measuring indicator (i) and
the fine scale (j), re-start the measuring process again by placing the measuring tool
elsewhere on the surface.
If the light-up ring (1) does not indicate readiness to measure when positioned on the
surface to be examined, the measuring tool has not been able to detect the base material
correctly.
– Press and hold the Drywall operating mode button (11) until the light-up ring (1)
lights up green. Take the measurement as normal.
