The V-Watch Personal Voltage Detector
detects electric fields. Make sure you un-
derstand these points efore proceeding:
• Electric fields surround every energized AC conductor.
• The closer you are to a conductor, the stronger the
field will be.
• Higher voltage means a stronger electric field and
a greater warning distance. Lower voltage means
a reduced warning distance.
• Electric fields are NOT blocked by plastics, dry wood
or clothing.
• Electric fields ARE blocked by ANY conductor such
as a metal cabinet or door, wet wood, metal fences,
green trees, a growing shrub or hedge & tall wet grass.
• The detector will not find cables buried under the
ground. The ground is a conductor and will block
electric fields.
• nsulation on a wire does not block the electric field
and does not affect warning distances.
• Underground primary cables are both insulated
AND shielded. The shield is a conductor, is grounded,
and will block the electric field.
• Molded cable terminators such as elbows are, like
the cables they are installed on, both insulated and
shielded and will block electric fields.
• Your body will block electric fields. Wear the detector
front and center and do not walk backwards.
• Do not use the detector while holding it in your hand.
Wrapping your fingers around the device will block
electric fields, preventing it from working properly. 5
