of metallic or electrically conductive building
materials.
For more precise location of the object, move
the detector repeatedly (3x) over the object.
The fine scale j is automatically activated in
all operating modes. Fine scale j indicates a
full amplitude when the object is below the
center of the sensor or when the maximum
amplitude of indicator i is reached. In the
operating modes "Drywall" and "metal", the
indication "CENTER" k will also light up.
When an item is very small and deeply
embedded, the indicator i reacts slightly.
Also, ring 1 continues to light up orange
with no sound signal. Move the detector
repeatedly over the object in horizontal
and vertical direction. Pay attention to the
amplitude of fine scale j and "CENTER"
indicator for precise detection.
If the wide object is detected with continuous
high amplitude of indicators i and j, ring 1
lights up orange. The duration of the high
amplitude corresponds approximately with
the width of the object.

OPERATINg mODES

The best results are achieved through
the selection of the operating modes. The
maximal detection depth for metal objects is
achieved in the operating mode "metal". The
maximal detection depth for "live" wires/
conductors is achieved in the operating
mode "live". The selected operating mode
can be recognized at any time via the green
illuminated operating mode indication 4.
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 and 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.
In the operating mode "Wood" all object
types are detected and indicated:
Wood substructures
–
magnetic metal, e.g. steel or iron
–
Non-magnetic metal, e.g. copper
–
pipe
– "live", e.g. a "live" conductor
Notes: In the Non-metal object indicator
i.e. wood or water-filled plastic pipes, water-
filled plastic pipes may also be detected.
display c may shown on display 3.
The on
Nails and screws on the surface may cause
wood substructure to be indicated as a metal
object on the display.
To Scan for Wood Objects:
- Press the wood detection mode button 10.
"Wood". The operating-mode indication 4
above button 10 lights up green.
- Position the detector onto the surface to be
scanned.
- Move the detector uniformly over the
surface without lifting it off or changing the
applied pressure. During the scan, the
contact pads 11 must always have contact
with the surface.
• When an object is detected, an amplitude
is displayed in the main detection indicator
i. Move the 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 1
lights up red and a steady tone sounds
as long as the detector is over the object.
The main measuring indicator i has the
greatest amplitude (as represented by
the number of bars shown in the main
detection indicator i) over the center of the
object.
To detect the object more precisely, move the
detector repeatedly (3x) back and forth over
the object. The fine scale j is automatically
activated in all operating modes. Fine scale
j indicates a full amplitude when the object is
below the center of the sensor or when the
maximum amplitude of detection indicator i
is reached. In the operating modes "Wood"
and "metal", the "CENTER" indicator k
lights up.
Notes:
• When display 3 indicates a continuously
high amplitude of detection indicator i and
fine scale j, restart the measuring procedure
again by positioning the measuring tool at a
different location on the surface.
• During a wood scan, metal objects may
also be detected. To help distinguish
between wood and metal objects, switch
to metal detection mode (see "scanning in
metal detection mode"). When an object
