Notes:

a) Some walls may contain metallised fibre, for fire-proofing, which will spread the area of voltage
pick-up. Placing your free hand on the wall may cancel the effect.
b) Rubbing or banging the unit on the wall may generate static electricity and cause false readings.
c) Because of the extremely small current required to cause a reading on the unit, an apparent 
false reading may be seen in some situations e.g. a conductor with poor insulation touching a
damp wall, will show a voltage on the wall. In this situation, the unit is indicating a potential
hazard which should be checked by a qualified electrician.

Wood Detection

3.3.1  With the Stud Detection face against the wall, hold the unit vertically as shown in Fig. 5 and turn 

the blue knob fully downwards.

3.3.2  Move the selector switch to the Stud Detector position.
3.3.3  Turn the blue knob upwards until the red LED and the buzzer come on.
3.3.4  Reverse the blue knob gently until the green LED is just illuminated and the buzzer ceases.
3.3.5 If 

the 

unit cannot be set, it needs to be adjusted. Refer to Section 3.5.

3.3.6  Move the unit horizontally across the wall. Refer to Fig. 6. Ensure that the detector face marked‘STUD’ is

placed against the wall, otherwise the green LED will go out and the calibration procedures will
need to be repeated.

3.3.7  When the edge of a batten or wall stud is under the unit’s groove, the red LED will come on and

the buzzer will sound. Mark this position on the wall.

3.3.8 Resume 

the movement of the unit. When the red LED and the buzzer go off, leaving the green

LED on, mark the position again. These marks indicate the edges of the batten or wall stud.
The mid-point between the two marks will be the centre of the batten or wall stud.

3.3.9

To locate horizontal battens or studs, place the unit on the wall as shown in Fig. 7 and use the
method outlined above.

Notes:

a) Stud detection can be carried out normally on papered walls. However, it may not function on some types of foil backed or 
metallic fabric surfaces.
b) If by chance the unit is placed over a wall batten or stud during calibration, the green LED will go out and the buzzer 
cease to sound when the edge of the batten, or wall stud, is under the  unit groove.
c) A double width may be found around door and window frames due to double battens or studs being encountered.
d) A solid wood header may exist in some doors or windows. The stud location will not be found if the unit is calibrated
on a normal wall first and then moved to the header area. It will indicate the presence of a header.
e) It is advisable to take several readings along the batten or stud as nails may change the apparent centre position.
f) Frequent re-calibration can help to avoid false readings.
g) We recommend carrying out voltage/metal detection to make sure that the detected batten or stud is not a pipe or 

cable. Note that some small securing screws or nails may be detected.

3.4

Maximising Accuracy

The sensitivity of the unit can be used to pin-point the exact position of pipes, cables or battens and studs. To do 
this, sweep the unit across the area in question, with light and buzzer sounding. After each sweep, gradually adjust 
the blue knob, until light and buzzer are no longer activated. Gently reverse the knob before each subsequent sweep, 
until the light and buzzer activate at the location of the pipe, cable, batten, or stud.

Unit Adjustment

3.5.1

METAL/VOLTAGE DETECTION ADJUSTMENT

3.5.1.1 Rotate the blue metal/voltage sensitivity knob to mid-position.
3.5.1.2 Slide the selector switch to the Voltage/Metal Detection position.
3.5.1.3 Using a small screwdriver, turn either the METAL or VOLTAGE detection trimmer, Refer to Fig. 1, as follows:

1) If  the green LED is on, slowly turn trimmer 1 CLOCKWISE until the red LED and buzzer just come on. Slowly 
turn back trimmer 2 until the green LED just comes on and the buzzer ceases. The unit is now correctly adjusted.

3.5.2

STUD DETECTION ADJUSTMENT

3.5.2.1 Rotate the blue stud sensitivity knob to mid-position.
3.5.2.2 Slide the selector switch to the Stud Detection position.
3.5.2.3 Hold the unit with stud face against the wall.
3.5.2.4 Adjust the trimmers, using a small screwdriver, as follows:

1) If the green LED is on, slowly turn trimmer 1 

CLOCKWISE

until the red LED and buzzer just come on.

2) Slowly turn back trimmer 2 until the green LED just comes on and the buzzer ceases. The unit is now correctly 
adjusted.

Note: Switch off the detector when it is not in use by moving the SELECTOR SWITCH to the MIDDLE POSITION.
