LIVE CABLE DETECTION
WARNING! The detector may not be able to accurately indicate live wires in walls if internal
equipment fails or is not properly operated, so do not rely solely on the instrument to identify the
presence of dangerous live wires. Other evidence, such as construction drawings or visual
identification of wiring or pipe entry points, should be used.
WARNING! If the wall contains live wires, do not take potentially dangerous measures. Be sure to
turn off power, gas, and water before drilling holes or nailing into the wall surface.
Maximum scanning depth: 50mm. (220V@50Hz / 110V@60Hz)
Press the cable detect button (7) to enter live
cable detection mode. The AC icon will appear
on the screen and the green indicator light will
illuminate.
If the detection signal strength display area
(18) shows any reading above 0% the
detector will need to be reset to zero. To return
to zero hold the detector on the surface to be
measured and press and hold the cable detect
button (7). The detection signal strength
display area will return to 0% and the green
indicator light will illuminate.
If the detection signal strength display area does not return to zero there is too much humidity or
static electricity in the area. There may be too many electrical appliances nearby and they should
be moved or turned off before trying to detect.
With the wall detector flat against the wall move the instrument left or right. As the instrument
gets closer to a hot wire, the scale on the detection signal strength display area (18) will
gradually rise and the intensity percentage will gradually increase. When you have located a hot
wire the red indicator light will illuminate and flash and a intermittent beep will be heard. Mark
this point with a pencil using the marker point on the top of the wall detector.
Note: Under certain conditions live wires cannot be detected with certainty. These can be behind
metal or conductive surfaces, Shielded in a metal conduit or be behind surfaces with high
moisture content. Concrete, brick, and ceramic surfaces all have shielding effects on the detector
and may generate false indications.
Live AC wires are more easily detected when the power-consuming device is connected to its
power supply and turned on.
‘Live’ wire signals will spread from both sides of the wire. The ‘Live’ wire alarm area looks much
larger than the actual wire.
AC signals come mainly from live wires but may also come from static or induced electricity in
the environment. Placing your hand on the wall next to the detector may help eliminate static and
inductive electricity.
