When the battery indication
k
flashes, measuring is still possible for approx. 10
minutes. When the battery indication
k
and the illuminated ring
1
(red) are flashing,
measuring is no longer possible and the battery or the rechargeable battery
respectively, must be replaced.
If the measuring tool is not used for a long period of time, the battery must be
removed. The battery can corrode or discharge itself over long periods.
Initial Operation
Protect the measuring tool against moisture and direct sun irradiation.
Switching On and Off
Before switching the measuring tool on, make sure that the sensor area 9 is not moist.
If required, wipe the measuring tool dry using a cloth.
If the measuring tool was subject to an extreme temperature change, allow it to adjust
to the ambient temperature before switching on.
To switch
on switch
on the measuring tool on, press any button. When switching
the measuring tool on with the wood-detection button
4
or with the metal-detection
button
5
, it will automatically be in the respective detection function.
When switching the measuring tool on with the “on/off” button
6
or with the “ZOOM”
button
3
, it will be in the detection function last used.
After a brief self-check, the measuring tool is ready for operation. When the
measuring tool is in the metal-detection function, the service readiness is indicated
through a check mark behind the “AutoCal” calibration indicator
g
.
To switch the measuring tool off, press the “on/off” button
6
.
If none of the measuring tool buttons are pressed for approx. 5 minutes, the
measuring tool switches off automatically in order to extend the service life of the
battery.
OPERATING MODES
The measuring tool detects objects below the sensor area
8
.
Detecting Metal Objects
When scanning for metal objects, press the metal-detection button
5
.
The metal detection indicator symbol c is indicated in the display and the illuminated
ring
1
lights up green
Position the measuring tool onto the surface to be scanned and
move it sidewards. When the measuring tool comes close to a
metal object, then the amplitude of the measuring indicator f
increases; when it moves away from the object, the amplitude
decreases. At the position of maximum amplitude, the metal
object is located below the centre of the sensor. As long as the
measuring tool is above the metal object, the illuminated ring
1
lights up red and a steady tone sounds.
To localise the object precisely, press the “ZOOM” button
3
and
keep it pressed while repeatedly (3x) moving the measuring
tool over the object. The “Zoom” function indicator d appears in
the display. The “Zoom” measuring indicator e has the greatest
amplitude over the centre of the metal object.
When very small or deeply embedded metal objects are being
detected and the measuring indicator f does not react, press
the “ZOOM” button
3
and keep it pressed while continuing to
move the measuring tool over the area. Observe only the zoom
measuring indicator e for the scan.
If there are any metal inclusions in the material being scanned, then a continuous
signal is indicated in the measuring indicator
f
. In this case, press the “ZOOM” button
3
and keep it pressed while continuing to move the measuring tool over the area.
Observe only the “Zoom” measuring indicator e for the scan.
If the metal object found is a magnetic (e.g. iron), then the indicator for magnetic
metals
h
is displayed. For non-magnetic metals, the indicator for non-magnetic
metals
i
is displayed. In order for the measuring tool to differentiate between the
metal types, it must be positioned above the detected metal object (the illuminated
ring
1
lights up red). For weak signals, the indication of the metal type is not possible.
For steel wire mesh and reinforcements in the scanned structural material, an
amplitude of the measuring indicator f is displayed over the complete surface. In this
case, always use the “Zoom” function for the scan. For steel wire mesh, it is typical
that the indicator for magnetic metals
h
is displayed directly above the rebar; the
indicator for non-magnetic metals
i
is displayed between the rebars.
