detecting needles, pins, junctions,
beams
To locate pins press the SELECT button until
•
the proper icon appears on the screen. Place
the device on the wall, keep the TEST button
pressed, and move the device slowly around
the area.
If the full result icon is displayed on the
•
screen and you hear a continuous beep, stop
moving the detector. These signals mean that
the device reached the edges of the sought
material. Mark this spot with the lining (do not
let the TEST button up!)
Continue to move the detector sideways
•
while keeping the TEST button pressed. If
the beeping stops and the icon is not visible
anymore, stop again and mark the spot. This
will be the other edge. The geometrical mean
of the two edges will be the exact mean of the
sought pin.
troubleshooting: If the LCD on the device
•
starts blinking and the beeping is not
constant, move the detector a few centimeters
and restart the operation.
note:
this check works nicely on a wallpapered wall. it can not
•
be used, however, on wrapped or metallic surfaces.
in case you accidentally put the device right on the top
•
of the pin, the device will most likely show nothing.
the surface must be even. after detection it is
•
recommended to perform a metal/phase detection as
well to rule out accidental metal pipe or electrical wire
findings. consider the fact that the device is capable of
detecting small metal objects as well, like safety pins,
needles, etc.
Metal detection
Select the metal detection mode with the
•
SELECT button. Keep the device away from any
metallic object during the selection and press
the TEST button. You will hear two small beeps.
After this, place the device on the wall and
move it around slowly on the desired area.
If the device signals a hit (full result icon and
•
beep), stop moving the device. Mark the spot,
but to not let up the TEST button.
Continue moving the detector in the desired
•
direction and when the signal stops, stop
again and mark the spot with the lining. The
geometrical mean between the two spots will
be the location of the metal inside the wall.
Phase detection
To ensure the highest possible sensitivity, keep
the device away from any kind of electronic
environment when turning it on and selecting
this function.
Select the AC mode and press the TEST button.
•
The device will beep shortly twice. Place the
detector on the wall and do not let the button
up. Move the device around carefully.
If the full result icon appears on the screen and
•
the device beeps, stop moving and mark the
spot. This will be one edge of the phase.
Proceed with moving the device (do not let
•
up the TEST button), if the signaling stops,
stop again and mark this spot too. The phase
conductor cable is between the two spots.
The geometrical mean of the two spots gives
•
the center of the phase. Naturally, if you mark
multiple spots on the wall, you are able to
determine the exact line of the cable (direction
of the cable).
note:
cables that are deeper than the detecting limit or ones
•
behind insulated or metal-wrapped walls can not be
detected with the device.
frequent and fast movement of the device generates
•
electricity, which may lead to incorrect results.

stray current: sometimes a small amount of electricity
•
is enough for the results to be incorrect. these occur
when stray current is present in e.g. wet walls, or
high humidity. the device will then show phase in
the measured area. in such cases it is advised to use a
voltage detector to ensure proper results.

nforMation
Shielded cables, conductors in metal piping or
•
cables running behind metallic or thick walls
can not be detected with the device.
Always drill with caution to avoid cutting into
•
cables running in the walls or in the floor!
When working near electricity, make sure to
•
turn off the main switch to ensure safety!
Based on the volume and quality of the pipes
•
and electric conductors the device can detect
electric cables as edges or pins.
To avoid suprises when measuring, make sure
•
that there are no similar objects or cables on
