gradually rotating the sensitivity control towards
the ‘OFF’ position to reduce the sensitivity and

NOTES FOR VOLTAGE DETECTION
• Some walls may contain metallic fiber for
fireproofing; this will spread the area of voltage
pick-up. Placing your free hand on the wall
may cancel the effect.
• Rubbing or banging the instrument on the wall
may generate static electricity and cause a
false reading.
• Only a small amount of electricity will trigger
the detector and can cause false readings,
such as a badly insulated cable touching a
damp wall.
• When the instrument gives a “No Voltage”
reading, check the unit on a known voltage
source before touching any conductor.
• It will not detect shielded conductors (i.e. those
in metal conduct, the unit only shows presence
of METAL).
• Never take risks! If unsure, consult a qualified
electrician.
• The instrument can operate in both Metal
Detecting and Stud Seeking models
simultaneously. Since plumbing may exist at
same location inside the wall (Figure 5), Metal
as well as Stud Indicators will come on
together. If the wiring that is carrying voltage is
located at the wall batten or stud inside the
wall (Figure 5), Voltage as well as Stud
indicators will come on together. In case of
abnormal performance when operating the
unit, replace with a fresh battery.
