Operating Modes
The measuring tool detects objects below the sensor area 9.
Detecting Metal Objects
When scanning for metal objects, press the metal-detection
button 6. 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 meas-
uring tool comes close to a metal object, then the
amplitude of the measuring indicator f increases;
when it moves away from the object, the ampli-
tude decreases. At the position of maximum
amplitude, the metal object is located below the
centre of the sensor (below the marking opening
2). 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 4 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 4 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 4 and keep it pressed
while continuing to move the measuring tool over the area. Ob-
serve only the "Zoom" measuring indicator e for the scan.
If the metal object found is a magnetic (e.g. iron), then the in-
dicator 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 in-
dication of the metal type is not possible.
For steel wire mesh and reinforcements in the scanned struc-
tural material, an amplitude of the measuring indicator f is dis-
played 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 dis-
played between the rebars.
