Safety notes
When using the Tester, if tip does not glow, voltage could still be present. The Tester indicates
active voltage in the presence of electrostatic fields of sufficient strength generated from the
source (MAINS) voltage. If the field strength is low, the Tester may not provide indication of live
voltages. 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:
● 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
Use caution with voltages above 30 V ac as a shock hazard may exist.
FOR USE BY COMPETENT PERSONS
Anyone using this instrument should be knowledgeable and trained about the risks involved with
measuring voltage, especially in an industrial setting, and the importance of taking safety
precautions and of testing the instrument before and after using it to ensure that it is in good
working condition.
The single-pole phase testing is not appropriate to determine whether a line is live or not. For this
purpose, the double-pole voltage test is always required.
Definition of measurement categories.
Measurement category II:
Measurement category II is applicable to test and measuring circuits connected directly to
utilization points (socket outlets and similar points) of the low-voltage mains installation. Typical
short-circuit current is < 10 kA.
Measurement category III:
Measurement category III is applicable to test and measuring circuits connected to the distribution
part of the building's low-voltage mains installation. Typical short-circuit current is < 50 kA.
Measurement category IV:
Measurement category IV is applicable to test and measuring circuits connected at the source of
the building's low-voltage mains installation. Typical short-circuit current is >>50 kA.
Read the instruction before use. If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
