Megohmmeter Models 5000N/5100/5110
These safety warnings are provided to ensure the safety of
personnel and proper operation of the instrument.
WARNING: HIGH VOLTAGE PRESENT
• Do not attempt to perform any tests with these instruments
until you have read the instruction manual.
• Safety is the responsibility of the operator!
• Tests are to be carried out only on non-energized circuits!
Check for live circuits before making resistance measure-
ments (safety check).
• These Megohmmeters are sources of high voltage, as is the
sample connected to them. All persons performing or
assisting in the tests must employ all safety precautions to
prevent electrical shock to themselves and to others.
®
• AEMC considers the use of rubber gloves to be an excellent
safety practice even if the equipment is properly operated and
correctly grounded.
• When testing capacitance samples, make sure that they have
been properly discharged and that they are safe to touch.
Dielectric insulation samples should be short-circuited for at
least five times the amount of time they were energized.
• Megohmmeters should never be used in an explosive
environment.
• Use the leads supplied with the megohmmeters. If they are
defective or worn, replace before testing.
