Operation
P r o t e c t t h e m e a s u r i n g t o o l
against moisture and direct sun
light.
Do not subject the measuring
tool to extreme temperatures
or variations in temperature. In
case of large variations in tem-
perature, allow the measuring
tool to adjust to the ambient tem-
perature before switching it on.
In case of extreme temperatures
or variations in temperature, the
accuracy of the measuring tool
and the display indication can be
impaired.
Use or operation of transmitting
systems, such as WLAN, UMTS,
radar, transmitter masts or mi-
crowaves, in the close proxim-
ity can influence the measuring
function.
Initial Operation
Switching On and Off
Before switching the measur-
ing tool on, make sure that the
sensor area 6 is not moist.
If re-
quired, dry the measuring tool us-
ing a soft cloth.
If the measuring tool was sub-
ject to an extreme temperature
change, allow it to adjust to the
ambient temperature before
switching on.
To switch on the measuring tool,
press the On/Off button 4 .
To switch off the measuring tool,
press the On/Off button 4 again.
When no button on the measuring
tool is pressed for approx. 5minutes
and when no objects are detected,
the measuring tool automatically
switches off to save the battery.
Switching the Audio Signal On/Off
When the measuring tool is switched
on, the audio signal can be switched
on or off by pressing the On/Off but-
ton
4 for a few seconds. When the
audio signal is switched off, indication
a appears on the display.
Method of Operation
(see figures A–B)
The measuring tool checks the base
material of sensor area
6 in measure-
ment direction z to the max. detec-
tion depth (see “Technical Data”).
Objects are detected that differ from
the material of the wall.
Always move the measuring tool in a
straight line over the surface apply-
ing slight pressure, without lifting it
off or changing the pressure. During
measurement, the contact pads
5
must always have contact to the sur-
face.
Measuring Procedure
After switching on, the illuminated
ring
1 lights up green.
Position the measuring tool against
the surface being detected and move
it toward the
x - and y -axis. When
the measuring tool comes closer to
an object, the amplitude in the main
scale
h increases and ring 1 lights up
yellow; when it is moved away from
the object, the amplitude decreases.
The main scale
h indicates the maxi-
mal amplitude above the object; ring
1 lights up red and an audio signal
sounds. For small or deeply embed-
ded objects, ring
1 can continue to
