SAFETY INFORMATION
Warning
To prevent possible electrical shock, fire, or
personal injury:
• If the Tester is used in a manner not specified
by the manufacturer, protection provided by
the Tester may be affected.
• Test on a known live source within the rated
AC voltage range of the product both before
and after use to ensure the Tester is in good
working condition.
• When using the Tester, voltage may be
present even if the tip does not glow. The
Tester indicates active voltage in the presence
of electrostatic fields of sufficient strength
generated from the source voltage. If the field
strength is low, the Tester may not provide
indication of live voltage. Lack of an indication
occurs if the Tester is unable to sense the
presence of voltage which may be influenced
by several factors including, but not limited to:
- Position of the earth conductors in the
environment under test
- 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 / differences
in socket design
- Condition of the Tester and batteries
• The Tester is not the appropriate tool to check
for the absence of voltage. Use a voltage
tester therefore.
• Do not use the Tester if it appears damaged or
is not operating properly. Closely examine the
probe tip for cracks or breakage before use. If
in doubt, have the Tester serviced.
• Do not apply more than the rated voltage as
marked on the Tester.
• When operating the Tester, keep fingers
behind the finger guard.
• Do not use the Tester if it is not flashing upon
power on.
• Use caution with voltages above 30 V AC as a
shock hazard may exist.
• Comply with local and national safety requirements.
• Use proper protective equipment as required
by local or national authorities.
