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
Note
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.
Avoid dusty and humid ambient conditions

Read and comply with the five safety rules:
■
1. Disconnect mains
2. Prevent reconnection
3. Test absence of voltage by approved means (establish absence of volt-
age using two-pole voltage indicators)
4. Ground and short-circuit
5. Protect adjacent live parts using covers
Do not expose the device to high temperatures for any length of time
■
Avoid dusty and humid ambient conditions
