Tip 3: To avoid interference while scanning, keep your free hand and
other objects at least 15 cm away from the device.
Tip 4: The device only finds the outer edge of metal structures set
into the wall for doors, windows and corners. Afterwards search
for the other edge of the metal structure. Slide the device sideways
across the wall. When the maximum indication appears you have
reached the metal structure's edge.
Tip 5: Ensure that you have really detected a metal object. To do
so, check on both sides whether other metal objects are present at
equal distances, usually at 30, 40 or 60 cm. Also check that it is a
metal object by scanning at several places directly above and below
the position of the first find.
Tip 7: Textured ceilings: The ceiling must be covered with
cardboard to protect it. In this case, perform detection with maxi-
mum sensitivity, i.e. calibrate the device in mid-air.
If electric wires or metal or plastic pipes are located near or in
!
contact with a plaster fibreboard panel, they may be identified
by the StarFinder as studs. Always switch off the power supply
when working near electric wires.

– Hold the device in midair where it is far away from any electric
conductors that may be live.
– Select the AC-Scan mode (Button 6). When this mode is
selected, the device performs an autonomous calibration
(AUTO-CALIBRATION). The device can be re-calibrated by pressing
the CAL button (7).
– CAL-LED (3) illuminates continuously: Now a measurement can be
performed. The device will now detect live electric conductors con-
cealed under plaster, wood panels and other non-metallic cladding.
It is not possible to detect live wires in dry walls with metal studs.
– Place the device against the wall.
– Move the device slowly across the surface.
