Introduction; International Electrical Symbols - AEMC 1060 User Manual

These safety warnings are provided to ensure the safety of personnel and
proper operation of the instrument.
• 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 measurements (safety check).
• High voltage is present, as is the sample connected to it. Anyone
performing or assisting in testing must follow 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 samples with a capacitive component, make sure they
have been properly discharged and are safe to touch. Dielectric insula-
tion 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.
• This instrument can be used on installations rated for 600V, Category III.
