6 Operation

6.1 Preparing the tool for use

CAUTION
Always drill at a safe distance from objects you have
detected.
1. Before switching the tool on, check that it is not in
contact with anything and is clear of the working
surface or metal objects.
2. Switch the tool on by pressing the on/off button.
All symbols are shown in the display within 1 second.
After carrying out a brief self-test, the tool begins to
calibrate itself automatically. The status LEDs light
green as soon as this has been completed.
While the tool is calibrating itself, hold it in the air at
least 30 cm (12 in) away from any metal objects and
away from the surface on which you are working.

6.2 Working with the tool

Check that the tool makes full contact with the surface
you wish to scan.
Use the tool only on smooth surfaces.
Bring the tool slowly and carefully into contact with the
surface to be scanned.
Do not move the tool at a speed greater than 20 cm/s (9
in/s).
6.2.1 Sweep scan method
In order to achieve best results, the tool should be used
with a sweeping motion (extended horizontal and vertical,
back and forward movements over the object). The series
of illustrations shows the sweep scan technique in use.
6.3 Locating objects
1. Switch the tool on and hold it at least 30 cm (12
in) away from any metal objects and away from the
surface on which you are working.
2. Carefully bring the tool into contact with the surface
to be scanned and then begin to move it sideways.
When the tool approaches a ferrous metal object (a
rebar), the "ferrous metal" symbol begins to blink,
the status LEDs light red and the amplitude of the
signal strength indicator rises and reaches its max-
imum when the tool is positioned over the center of
the object. If the tool is moved further until it is past
the ferrous metal, the status LEDs light green and
the signal strength indicator shows a decreasing
value. To obtain an exact indication of the position
of the rebar, the tool must be moved back in the
opposite direction until the status LEDs again light
red and the signal strength indicator shows the max-
imum value. Use the marking pen supplied to mark
the position of the ferrous metal object through the
marking opening in the tool. If the loudspeaker has
been activated, a constant audible signal is emitted
so long as the tool is positioned over the ferrous
metal object.
When the tool approaches a non-ferrous metal ob-
ject (copper, aluminium), the "non-ferrous metal"
symbol begins to blink, the status LEDs light red
and the amplitude of the signal strength indicator
rises and reaches its maximum when the tool is po-
sitioned over the center of the object. If the tool is
moved further until it is past the non-ferrous metal
object, the status LEDs light green and the signal
strength indicator shows a decreasing value. To ob-
tain an exact indication of the position of the rebar,
the tool must be moved back in the opposite dir-
ection until the status LEDs again light red and the
signal strength indicator shows the maximum value.
Use the marking pen supplied to mark the position
of the non-ferrous metal object through the marking
opening in the tool. If the loudspeaker has been ac-
tivated, a constant audible signal is emitted so long
as the tool is positioned over the non-ferrous metal
object.
