VolTect™ Non-contact Voltage Detection
WARNING!
W
• If the instrument is used in a manner not specified by the manufacturer,
protection provided by the tester may be impaired.
• Test on a known energized source within the rated ac voltage range of
the instrument both before and after use to ensure the instrument is in
good working condition.
• The non-contact voltage detection function is always on. When the
probe or antenna is close to energized wires, LED flashes and beeps.
Non-contact voltage detection will be disabled when LAMP TEST button
is pressed.
• When using the instrument, if LED indicator does not glow or
the instrument does not beep, voltage could still be present. The
instrument indicates active voltage in the presence of electrostatic
fields of sufficient strength generated from the source voltage. If the
field strength is low, the instrument may not provide indication of live
voltage. Lack of an indication occurs if the instrument is unable to sense
the presence of voltage which may be influenced by several factors
including, but not limited to:
- Shielded wire/cables
- Thickness and type of insulation
- Distance from the voltage source
- Fully-isolated users that prevent an effective ground
- Receptacles in recessed sockets or differences in socket design
- Condition of the instrument and batteries
