This advanced electronic detector can detect and

locate wooden studwork, metal and AC voltage,

providing a clear indication of concealed objects

prior to drilling, nailing or screwdriving.

1. Find wood and metal studs.

2. Find and identify a stud centre

3. Find AC voltage and scan to trace live cables.

4. Metal scanning to find, nails, pipes, rebar and

other hidden metal objects.

This detector may be used to carry out the

following operations:

1. Find metal pipes in concrete.

2. Find wooden studwork

3. Find electrical box, exhaust vent, conduit,

rebar, and ducting.

4. Find and trace live cable behind ceiling, floors

and walls.

INTRODUCTION

FEATURES

APPLICATION

3. Bottom Signal LED

There are 2 bottom signal LEDs.

In most situations, the two bottom signal LEDs turn

on first when the detector approaches the target

object.

4. Power LED

It lights as a power indicator when the TEST button

is pressed.

5. TEST button

Use to turn the detector on. You must depress and

hold this switch down to calibrate the detector or

when you wish to perform detection operation.

6. Selector switch

A three position switch used to select the required

scan mode. Available scanning modes are:

STUD -

------

Stud scan mode

METAL ------ Metal scan mode

AC WIRE --- AC voltage scan mode

7. MARK button

In some conditions it is not suitable to make marks

with pencil. You can press this button to mark dots

on the wall surface.

Stud Detection Procedure

1. Set the selector switch to "STUD" position.

2. Calibration:

Place the unit against wall. Depress and hold the

TEST button down, the detector will begin calibration.

When it sounds two beeps, the calibration is

complete. Always keep the TEST button depressed

throughout all the following procedures.

3. Detection:

a. Place the detector on the surface and slowly move

the unit sideways (fig 1). When the detector moves

closer and closer to the stud, the signal LEDs will

light sequentially from bottom to the top. When the

top signal LED lights and the built-in buzzer

sounds continuously, the unit has detected the

stud's edge. Stop moving and mark a spot in the

detectors groove on the walls surface (fig 2).

OPERATING INSTRUCTIONS

Fig.1 Fig.2 Fig.3

b. Continue moving sideways across wall until all the

signal LEDs and the buzzer turn off, then reverse

direction and locate opposing edge by using the

same procedure. When the LED lights and buzzer

sounds continuously stop moving and mark a spot in

the detectors groove on the walls surface (fig 3), the

midpoint between two marks is the centre of the stud.

Note

1. Stud detection can be carried out on standard

plasterboard walls. However, it may not function on

some types of foil backed or metallic fabric surfaces.

2. If the detector is placed over a wall batten or stud when

performing a calibration, the detector will not work correctly.

3. The surface of wall along which you want to detect

should be flat and dry.

4. We recommend that you also carry out a metal detection

scan to ensure that the detected batten or stud is not a

metal pipe. Please note that some small securing

screws or nails or metal objects may be detected.

5. Keep your other hand away from the detector when

carrying out a scan.

6. Wall studs will be approximately 40cm to 60cm apart

with a width of about 3.8cm.

7. If two studs are adjacent the unit may not detect them

accurately.

8. After you release the TEST button, the detector must

perform a calibration sequence again before use.

9. Do not move the detector too quickly as the RED

signal LEDs will not light sequentially.

Metal Detection Procedure

1. Set the selector switch to the "METAL" position.

2. Calibration:

Hold this detector in air away from any metal object,

Depress and hold the TEST button down, the

detector will begin calibration. When it sounds two

beeps, the calibration is complete.

Always keep the TEST button depressed throughout

all the following procedures.

3. Detection:

Place the detector on the surface and slowly move

the unit sideways. When the unit moves closer and

closer to a metallic object, the signal LEDs will light

sequentially (fig 1). When the top signal LED lights

and the buzzer sounds continuously, the unit detects

the metallic object's edge, stop moving and mark a

spot in the groove (fig 2).

b. Continue moving sideways across wall until all the

signal LEDs and the buzzer turn off, then reverse

direction and locate the opposing edge by using the

same procedure. When the LED lights and buzzer

sounds continuously stop moving and mark a spot

in the detectors groove on the walls surface(fig 3), the

midpoint between two marks is the centre metal object.

AC Voltage Detection Procedure

For maximum sensitivity, begin by placing the detector in a

position away from live wiring.

1. Set the selector switchtothe "AC WIRE" position.

2. Calibration:

Depress and hold the TESTbutton down , the detector

will begin calibration. When it sounds two beeps, the

calibration is complete. Always keep the TESTbutton

depressed throughout all the following procedures.

3. Detection:

a. Place the detector on the surface and slowly move the

unit sideways (fig 1). When the top signal LED lights

and buzzer sound continuously, stop moving, the

detector has located the edge of a live wire, mark a

spot in the groove on the walls surface (fig 2).

b. Continue moving sideways across wall until all the

signal LEDs and the buzzer turn off, then reverse

direction and locate the opposing edge by using the

same procedure. When the LED lights and buzzer

sounds continuously stop moving and mark a spot in

the detectors groove on the walls surface (fig 3), the

midpoint between two marks is the centre of live wire.

Fig.1 Fig.2 Fig.3

Note

1. Wires deeper than the detection limit from surface, in

conduit or behind plywood shear wall will not be

detected use caution when using the detector under

these circumstances.

2. Rubbing or banging the unit on the wall may generate

static electricity and cause a false indication.

3. Leakage Currents

Because of the extremely small current required to

cause a reading on the detector, an apparent false

reading may be seen in some situations, If a live wire

with poor insulation is touching a damp wall, the detector

will show a voltage on the walls surface Inthis situation,

the detector is indicating a potential hazard which should

be checked using a voltmeter.

1. Depending on the proximity of electrical wiring or

pipes to the wall surface, the unit may detect

them in the same manner as studs.

Caution should always be used when nailing,

sawing, or drilling into walls, floors, and ceilings

that may contain wiring or pipes.

2. When working near electrical wires, always turn

off the mains power.

3. To avoid unexpected problems please be aware

that different types of material may be close

together. A stud, joist, pipe, metal object or wire

may be adjacent to each other.

4. If you do not intend to use the detector for an

extended time, please remove the battery before

storage.

5. For an accurate locating result, it is recommended

that user repeats the detection scan around the

detected object in different directions.

6. Shielded wires or live wires encased in metal

conduits, casings, metal walls or thick, dense

walls will not be detected.
