The V-Watch Personal Voltage Detector
detects electric fields. Make sure you
understand these points before 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 and tall wet grass.
• The detector will not find cables buried under the ground.
The ground is a conductor and will block electric fields.
• Insulation 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.
