DETECTING WOODEN OBJECTS
When scanning for wooden objects, press the wood-detection button
4
. The wood detection indicator symbol
B
and the “Zoom” function in-
dicator
D
are indicated in the display and the arrow below the “Zoom”
function indicator
D
flashes. The “AutoCal” calibration indicator
G
and the
illuminated ring
1
go out.
Position the measuring tool onto the surface being scanned.
Then press the “ZOOM” button
3
and keep it pressed. Now
the illuminated ring
1
lights up green, the “AutoCal” calibra-
tion indicator
G
is displayed again, the “Zoom” function indi-
cator
D
as well as the arrow below it go out.
With the “ZOOM” button
3
pressed, move the measuring tool uniformly
above the structure without lifting it off or changing the applied pressure.
During the scan, thefelt pads
7
must always have contact with the struc-
ture.
When a wooden object is detected, an amplitude is displayed in the
measuring indicator
F
. Move the measuring tool over the surface repeat-
edly to localise the wooden object more precisely. After moving over the
same area several times, the wooden object can be indicated quite ac-
curately: The illuminated ring
1
lights up red and a steady tone sounds
as long as the measuring tool is over the wooden object. The measur-
ing indicator f has the greatest amplitude over the centre of the wooden
object. The “Zoom” measuring indicator e is inactive when scanning for
wooden objects.
CAUTION:
When having placed the measuring tool onto the surface to be
scanned under which a wooden object is coincidentally located, and hav-
ing moved it over thesurface, the measuring indicator f, the arrow below
the “Zoom” function indicator d and the illuminated ring
1
flash red. In this
case, start the scan again by repositioning the measuring tool somewhat
offset onto the structure and pressing the “ZOOM” button
3
again.
When scanning for wooden objects, metal objects are sometimes also
indicated as objects found at depths between 20–50 mm. To distinguish
between wooden and metal objects, switch to the detecting-metal func-
tion (see “Detecting Metal Objects”). When an object is indicated at the
same location in this function, then it is clearly a metal object and not a
wooden object. To continue searching for wooden objects, switch back to
the detecting-wood function.
