Scanning in Wood-Detection Mode
The wood-detection mode actually detects
more than just wood substructures (studs and
joists). It may also detect metal and other
dense materials such as water-filled pipes
plastic pipes near the back of the surface in
the wall or ceiling. To help identify wood
substructures, first conduct a metal scan and
mark the location of any detected metal items.
Then conduct a scan in the wood-detection
mode. Items that are detected in the wood-
detection mode but not in the metal-detection
mode are items that are possibly wood
substructures.
To scan for wood objects,
1. Press the wood detection mode button 5.
• The wood mode indicator band the
“ZOOM” indicator dare shown in the
display, the arrow below the “ZOOM”
indicator dflashes, and the “AutoCal”
calibration indicator gand the illuminated
ring 1go out.
2. Position the multi-detector onto the surface
to be scanned.
3. Then press the “ZOOM” button* 4AND
KEEP IT PRESSED.
• Now the illuminated ring 1lights up green,
the AutoCal” calibration indicator gis
displayed again, and the “ZOOM” indicator
d as well as the arrow below it go out, all
indicating that the multi-detector is calibrated
for the wood scan.
4. After the multi-detector has
been calibrated and while
continuing to press the
“ZOOM” button 4, move the
multi-detector uniformly over
the surface without lifting it off
or changing the applied
pressure. During the scan, the
felt pads 8must always have contact with the
surface.
• When an object is detected, an amplitude is
displayed in the main measuring indicator f.
Move the multi-detector over the surface
repeatedly to locate the object more
precisely. After moving over the same area
several times, the object can be indicated
quite accurately: The illuminated ring 1lights
up red and a steady tone sounds as long as
the multi-detector is over the object. The
main measuring indicator fhas the greatest
amplitude (as represented by the number of
bars shown in the main measuring indicator f)
over the center of the object.
Note: While the “ZOOM” button 4is pressed
during the wood scan, the “ZOOM” feature
and ZOOMmeasuring indicator eare inactive.
Notes:
• If the scan (and thus calibration) starts
over a dense object, such as a stud or a
pipe, and is then moved across the
surface, the main measuring indicator fand
the arrow below the “ZOOM” function
indicator dflash and the illuminated ring 1
flashes red, indicating a calibration failure. If
this happens, move the detector horizontally
to a different location and start the scan
again (Fig. 4).
• During a wood scan, metal objects at
depths between 3/4" and 2" may also be
detected. To help distinguish between
wood and metal objects, switch to metal-
detection mode (see “Detecting Metal
Objects”). When an object is indicated at the
same location in the metal-detection mode,
then it is likely a metal object or a wood stud
or joist with nails or screws in it. To continue
searching for wood objects, switch back to
the wood-detection mode.
