Function / Application
Multiple integrated sensors make StarFinder Plus by Laserliner a highly efficient detecting
device for locating wall beams and joists in drywall structures and finding live lines. The
StarFinder Plus is equipped with an LC display with user guide, ensuring easy and reliable
operation. Acoustic and optical detection signals to locate objects facilitates handling and
ensures a high level of functional reliability.

LC display
ON / OFF
Switching measuring mode (MODE)
Manual calibration (CAL)
Open the battery compart-
ment on the housing‘s
rear side and insert a 9V
battery. Correct polarity
must be observed.
Insert battery Switch on: Briefly press the
On/Off button (4).
Switch off: Keep the On/Off
button (4) pressed for 2 seconds.
AutoShutOff: The device will
automatically switch itself off
about 30 seconds after the last
measurement.
Operation
Auto-Calibration
The automatic calibration is performed in AC-SCAN measure-
ment immediately when the device is switched on and when the
measuring mode is switched. During calibration, the display shows
„CAL“. Do not move the device during this process. Once „CAL
OK“ appears on the display, tracing can be started.
Calibration
Manual calibration
Pressing the CAL button (5) manually calibrates the device. This
allows measurements to be restarted and objects to be isolated
more precisely.
Maximum sensitivity is achieved when the device is held in the air
while calibrating. This can be useful for AC-SCAN measurements.
Always switch off the power supply
when working in STUD-SCAN mode
in the vicinity of electric conductors.

Briefly press the Mode button (4).
AC-SCAN (Locating live lines directly under non-metallic cladding)
STUD-SCAN (Detecting wooden wall beams and joists as well as
metal in drywall structures under non-metallic cladding)
Select measurement mode
The device and the wall must maintain contact during calibration in STUD-SCAN
mode and throughout the entire measurement process. A hand should remain at
the device the entire time as well.
!
Detecting wooden wall beams and joists as well as metal in drywall
structures, e.g. under gypsum fibreboard, wood panels or other
non-metallic cladding.
– Select STUD-SCAN (button 4)
– ON WALL: Place the tool against the wall
– PRESS CAL: Press the calibration button (5)
and wait until calibration is completed: CAL OK
– MOVE: Move the tool slowly across the surface.
Measuring in STUD-SCAN mode
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 Plus as studs.
!
Special things to note with various materials
It may not be possible to detect wooden studs or joists through the following materials:
– Ceramic floor tiles
– Fitted carpeting with padded backing
– Wallpaper with metal fibres or metal foil
– Freshly painted, damp walls. These must have dried for at least one week.
Tip 1: The position between the two markings is the mid-point of the stud.
Tip 2: The position where you start is important: First place the tool in a position where
you know there is no stud. Otherwise, the message “ERROR” will appear in the display.
To remedy: Move the tool to another position a few centimetres away and start
measuring again.
Tip 3: To avoid interference while scanning, keep your free hand and other objects at
least 15 cm away from the StarFinder Plus.
Tip 4: The StarFinder Plus will only find the outside edge of double studs and headers
which may be fitted around doors, windows and corners.
Tip 5: Ensure that you have really detected a stud. To do so, check on both sides whether
other studs are present at equal distances, usually at 30, 40 or 60 cm. Also check that it is
a stud by scanning at several places directly above and below the position of the first find.
Tip 6: Textured ceilings: The ceiling must be covered with cardboard to protect it. In this
case, use the DeepScan function.
Note: If an object is deep inside a wall, the device may not indicate it clearly.

Tip 1: Manual calibration should be performed near the place found last as shown in
Image B/C. Repeat this step as needed.
Tip 2: Because of static charges, electric fields may be detected at the side of the actual
position of the wire. To carry away these charges, lay your free hand on the wall.
Tip 3: Move the tool slowly as friction can generate interfering electric charges.
Tip 4: If you suspect that wires must be present but cannot find any, this may be because
they are shielded in conduits. Use STUD-SCAN in order to localise conduits.
Tip 5: Metal in walls (e.g. metal studs) transmit electrical fields and may therefore cause
interference. In this case, switch to STUD-SCAN in order to find the wire.
Tip 6: The position where you start is important: To achieve maximum sensitivity, start by
placing the device in a position which is known not to be near live wires.
Note: If an object is deep inside a wall, the device may not indicate it clearly.
Continuous current monitoring in unshielded wires as soon as an electrical field
is detected.

calibration
Isolate an object to be
measured by passing
over it several times.

calibration
Wires which are at a depth of more than 4 cm may not be detected.
!
For localising live wires directly beneath the plaster or behind wooden panels and other
non-metallic panelling. It is not possible to detect live wires in dry walls with metal studs.
– Select AC-SCAN (button 4).
– As soon as the display switches from CAL to CAL OK, you can move the device.
– MOVE: Move the tool slowly across the surface.
