When detecting foreign bodies, the detector must be vertically placed to the wall. Press the
Foreign Object Detection Button (6) and keep the detector stationary for 1-3 seconds and wait for
the completion of the instrument calibration. Once the green light is illuminated the calibration is
complete.
Place the detector on the surface you wish to
scan and move the instrument slowly to the
left or right. As the instrument gets closer to
the edge of the wooden object, the scale on
the detection signal strength display area (18)
will gradually rise and the intensity
percentage will gradually increase. The Edge
Display Icon (17) will also gradually appear.
When the detector is at the edge of the
wooden block the ‘Edge’ character will be
displayed. Continue to move the detector in
the same direction until the Edge Display Icon
(17) displays the other half of the scale. When the detector locates the middle of the wooden
block the ‘Center’ character will be displayed and the red indicator light will illuminate. A beep
will also be heard. We recommend marking both left and right edges and the center point with a
pencil using the marker point on the top of the wall detector. Continue moving the detector
across the wall and if the instrument cannot detect any more wooden blocks and the green light
is illuminated the detection operation is complete.
Note: Repeated detection will give you a more accurate result.
If the red indicator light on the detector flashes, the AC current icon flashes and a repeated short
beep is heard it has detected both a foreign body and AC signal.
If the detector is only showing a flashing AC current icon then only a AC current has been
detected.
Due to various environmental factors the instrument may not be automatically calibrated and
there may be a wrong alarm signal. If this happens the detector will need to be manually
calibrated. To calibrate short press the Foreign Object Detection Button (6) and wait for the green
light to illuminate. Make sure the detector is away from any wooden block when calibrating.
If you receive unstable scan results it may be due to moisture in the wall cavity or drywall,
moisture, or recently applied paint or wallpaper that is not completely dry. While moisture may
not always be visible, it can interfere with the detectors sensor. Please let the walls dry for a few
days before using the detector.
