Working With The Tool - Hilti PS 35 Mode D'emploi

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
movements over the object). The series of illustrations
show the sweep method in use. When the tool is switched
on for the first time, it displays an animated training
program that shows how the tool should be used to scan
a surface.
6.3 Locating objects in standard mode
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.
The tool activates standard mode after completing
automatic calibration.
The depth measurement units (mm or in) are shown
in the display and the status LEDs light green.
The tool is ready to be used for locating objects.
2. Carefully bring the tool into contact with the surface
to be scanned and then begin to move it sideways.
NOTE Deactivate the limited depth scan setting
if you wish to detect ferrous metal without depth
limitation.
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-
20
imum when the tool is positioned over the center of
the object.
In the meantime, the depth measurement is shown
in the display.
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
object, the tool must be moved back in the opposite
direction until the status LEDs light red and the
signal strength indicator shows the maximum 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
positioned 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 obtain an exact indication of the position of the
object, the tool must be moved back in the opposite
direction 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 activated, a constant
audible signal is emitted so long as the tool is
positioned over the non-ferrous metal object.
6.4 Locating objects consisting solely of ferrous
metal
1. Switch the tool on.
Activate the ferrous metals detection mode in the
menus and deactivate the non-ferrous metals de-
tection mode.
2. The limited depth scan mode may be activated if
desired.
3. Then follow the steps described in the section "Loc-
ating objects in standard mode" (for ferrous metals).
