OVERVIEW

Clarke-CDM65-Super-Detector-1

INSERTING THE BATTERY

Remove the battery door on the rear of the unit.
Connect a 9V PP3 battery to the battery clip.
Place the battery into the compartment.
Replace the battery door.

AC VOLTAGE DETECTION

Set the selector switch to the AC WIRE position.
Hold the unit in the air away from any metal objects.
Press and hold the TEST button.
The unit will beep twice when calibration is complete. Do not release the TEST button.
Keep holding the TEST button and place the unit on the wall, slowly move the unit sideways across the wall.
As you approach a live wire, the signal lights will light up sequentially, the buzzer will sound when
you reach the edge of the live wire, when this happens mark the point by placing a pencil mark
in the grove on top of the unit.
Carry on moving the unit in the same direction until all of the signal LEDS go out and then reverse direction.
Once again, mark the point at which the top LED lights up and the buzzer sounds by placing a pencil mark in the grove on top of the unit.
The centre of the live wire is located mid way between the two pencil marks.

Notes

Some walls containing metal fibres (used in fireproofing) will cause the detector to register a voltage over a wider area.
Rubbing or banging the wall may generate static electricity, causing a false reading.
Touching a damp wall being tested may also cause a false positive reading.
The unit will not detect wire inside metal shielding or trunking.

METAL DETECTION

Set the selector switch to the METAL position.
Hold the unit in the air away from any metal objects.
Press and hold the TEST button.
The unit will beep twice when calibration is complete. Do not release the TEST button.
Keep holding the TEST button and place the unit on the wall, slowly move the unit sideways across the wall.
As you approach a metal object, the signal lights will light up sequentially, the buzzer will sound when you reach the edge of the metal object, when this happens mark the point by placing a pencil mark
in the grove on top of the unit.
Carry on moving the unit in the same direction until all of the signal LEDS go out and then reverse direction.
Once again, mark the point at which the top LED lights up and the buzzer sounds by placing a pencil mark in the grove on top of the unit.
The centre of the metal object is located mid way between the two pencil marks.
Wearing rings or other hand jewellery may cause a false reading.

STUD DETECTION

Set the selector switch to the STUD position.
Place the unit against the wall, press and hold the TEST button.
The unit will beep twice when calibration is complete. Do not release the TEST button.
Keep holding the TEST button and slowly move the unit sideways across the wall.
The buzzer will sound when you reach the edge of the studding, when this happens mark the point by placing a pencil mark in the grove on top of the unit.
Carry on moving the unit in the same direction until all of the signal LEDS go out and then reverse direction.
Once again, mark the point at which the top LED lights up and the buzzer sounds by placing a pencil mark in the grove on top of the unit.
The middle of the studding is located mid way between the two pencil marks.

Always check that the “STUDDING” that you have detected is not a metal pipe, see page 6.

NOTES

You can use the detector on wallpaper, however it may not be effective on some types of foil backed wallpapers.
If the unit is placed over studding during the calibration, the unit will not work, simply re-calibrate the unit 150 mm away from the last place.
The surface of the wall should be dry and flat.
Always keep your free hand away from the wall during detection.
If you release the test button at any time during detection, you will need to carry out the calibration procedure again.
Knots in wood can cause false readings to occur.
Normally, studding is placed at intervals of 40 – 60 cm.

TIPS

Re-calibrate the unit frequently to avoid inaccurate readings.
Take several readings vertically above, below, to the left and right to confirm the reading.

DETECTION DEPTHS

Iron Pipe (25mm) 30 mm
Studding (30 x 30mm)18 mm
AC Voltage (90-250V @ 50/60 Hz) 50 mm

Detection depth can vary due to moisture content and texture of the wall, paint etc.
