Degree of protection
*depending on operating mode, material and size of the objects, as well
as material and condition of the base material
**less scanning depth for wires/conductors that are not "live"
In terms of accuracy, the measuring result can be inferior in case
of unfavourable surface quality of the base material.

Alkali-manganese batteries are recommended for the meas-
uring tool.
To open the battery lid 14, press the latch 15 in the direction
of the arrow and fold up the battery lid. Insert the supplied
battery. Pay attention that the polarity is correct, according to
the representation on the inside of the battery lid.
The battery indicator h always indicates the current battery
status:

If the measuring tool is not used for a long period of
GMS 120
time, the battery must be removed. The battery can cor-

tures or variations in temperature. In case of large var-
iations in temperature, allow the measuring tool to ad-

Initial Operation

Switching On and Off
Before switching the measuring tool on, make sure that
the sensor area 12 is not moist. If required, dry the meas-
uring tool using a soft cloth.
If the measuring tool was subject to an extreme tem-
perature change, allow it to adjust to the ambient tem-
perature before switching on.
To switch on the measuring tool, press the On/Off button 5.
To switch off the measuring tool, press the On/Off button 5
again.
When no button on the measuring tool is pressed for approx.
5 minutes and when no objects are detected, the measuring
tool automatically switches off to save the battery.
Switching the Display Illumination On/Off
The display illumination can be switched on/off with display-
illumination button 6.
Switching the 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, indication a
appears on the display.
