1. PRECAUTIONS/SAFETY MEASUREMENTS
This instrument complies with safety standards related to
electronic measuring instruments. For your own safety and
to avoid damaging the instrument follow the procedures
described in this instruction manual and read carefully all
notes preceded by this symbol
CAUTION
Avoid measuring in humid or wet places
Avoid measuring in rooms where
explosive gas, combustible gas, steam or
excessive dust is present
Keep you insulated from the object under
test
Do not touch exposed metal parts such
as test lead ends, sockets, fixing objects,
circuits etc...
conditions such as breakages,
deformations, fractures, leakages of
battery fluid, blind display etc...
The following symbols are used in user manual and on the
meter:
CAUTION - refer to the instruction manual -
an improper use may damage the instrument
or its components
AC Voltage
DC Voltage
CAUTION: this symbol indicates that
equipment, its accessories and battery shall
be subject to a separate collection and correct
disposal
2. GENERAL DESCRIPTION
The instrument is able to detect::
Presence of wooden studs and hidden conductive objects
Presence of hidden metal objects
Presence of hidden AC live wires
inside walls, ceilings, concrete walls and other common
materials. The instrument emits a sound and shows a signal
on the display after identifying the object's edge so as to
easily identify its central position.
Each of these functions can be selected by pressing the
MODE button. There are also the TEST button for the start-
up and initial calibration and an analogical graphic bar that
identifies the signal strength. The instrument is equipped
with an Auto Power OFF device which automatically turns off
after 30s of idleness.
3. PREPARATION FOR USE
3.1. Initial checks
This instrument was checked both mechanically and
electrically prior to shipment. All possible cares and
precautions were taken to let you receive the instrument
under perfect conditions. Notwithstanding we suggest you to
check it rapidly (any damage may have occurred during
transport – if so please contact the local distributor from
whom you bought the item). Make sure that all standard
accessories mentioned in § 7 are included. Should you have
to return back the instrument for any reason please follow
the instructions mentioned in § 8.
3.2. Supply voltage
The instrument is powered by 1x9V battery type IEC 6F22
included on meter. When battery is low the symbol " " is
displayed. To replace/insert the batteries follow the
instructions indicated in § 6.
3.2. Storage
After a period of storage under extreme environmental
conditions exceeding the limits mentioned in § 7 let the
instrument resume normal operating conditions before using
it.

5. OPERATIVE INSTRUCTIONS
5.1. Wooden/conductive objects and metals detection
1. Switch on the instrument by pressing the TEST key for 2s
2. Press the MODE key to select the detection of wooden
studs or conductive objects (symbol shown on the
display) or the detection of metal objects (symbol
shown on the display
3. Place the instrument on the surface that encloses the
object being searched and press the TEST key in order to
perform initial calibration the instrument. A short sound,
the brief lighting of the bar and the or symbol flashes
on the display to indicate that the instrument is ready for
scanning
4. Hold the instrument in the lower part and move it slowly
on the surface from left to right (see Fig.3 - left part)
Fig. 3: Scanning of conductive object
5. When the central bar is shown on the display (see Fig. 3 –
middle part) the instrument emits a continuous sound.
Stop the instrument and mark the initial edge of the object
on the surface
6. Continue the search scan along the surface until the
graphic bar disappears and the sound stops (see Fig.3 -
right part). Mark the final edge of the object
7. Repeat the previous steps several times in order to
accurately locate the hidden object
8. Long press the MODE key to switch off the instrument
CAUTION
The instrument is able to detect any
material with a minimum of conductivity,
but is NOT able to detect the presence
of plastic materials
The calibration must be performed on a
homogeneous and uniform surface in
order to avoid reading problems. In the
case of a rough surface, place the
instrument on a piece of cardboard
The presence of metal parts inside the
walls can affect the test result
To avoid interference, keep the free hand
at least 15cm (6in) away from the
scanning surface
The instrument does NOT scan
conductive materials in the presence of
walls with depth greater than 18mm
(0.7in) and with objects of minimum size
30x30mm (1.2x1.2in)
The instrument does NOT scan metals
materials in the presence of walls with a
depth greater than 30mm (1.2x1.2in)
and with objects with a diameter greater
than 25mm (1in)
5.2. AC live wires detection
1. Switch on the instrument by pressing the TEST key for 2s
2. Press the MODE key to select the detection of AC voltage
live wires (symbol shown on the display)
3. Place the instrument on the surface that encloses the
object being searched and press the TEST key in order to
perform a first calibration. A short sound, the brief lighting
of the bar and the symbol flashes on the display to
indicate that the instrument is ready for scanning
4. Hold the instrument in the lower part and move it slowly
on the surface from left to right (see Fig.4 - left part)
Fig. 4: Scanning of AC live wires
5. When the central bar is shown on the display (see Fig. 4 –
middle part) the instrument emits a continuous sound.
Stop the instrument and mark the initial edge of the object
on the surface (1st marker)
6. Continue the search scan along the surface until the
graphic bar disappears and the sound stops (see Fig.4 -
middle part)
7. Stop the instrument and mark the 2nd marker on the
surface (see Fig.4 - middle part)
8. Position the instrument in the space between the 1st and
2nd marker and press the TEST key in order to perform a
second calibration
9. Perform a new scan as indicated in the previous points by
slowly moving the instrument from left to right in the space
between the 1st and 2nd marker
10. Mark the surface with the 3rd marker and the 4th marker
(see Fig. 4 - right part)
11. The hidden object will be in the space between the 3rd
and 4th marker. The distance between these two new
markers must be about 6cm (2in) (almost the size of the
instrument itself
CAUTION
The calibration must be performed on a
homogeneous and uniform surface in
order to avoid reading problems. In the
case of a rough surface, place the
instrument on a piece of cardboard
To avoid interference, keep the free hand
at least 15cm (6in) away from the
scanning surface
The instrument does NOT scan metals
materials in the presence of walls with a
depth greater than 50mm (2in)
6. BATTERY REPLACEMENT
