Auto-Ohm Operating Procedures

SAFETY SUMMARY
The following safety precautions must be
observed during all phases of test set-up, test
hookups, testing, and test-lead disconnects.
Do Not Service or Test Alone
Do not perform test procedures or service
unless another person is also present who is
capable of rendering aid and resuscitation.
Avoid Contact with High Voltage
Because electrical utility station
environments contain high voltages and
currents, there is always the possibility of
personal contact with an unexpected lethal
voltage generated by magnetic induction
and/or electrostatic leakage from nearby live
circuitry. When test units are connected to
deenergized ("dead") power lines, regardless
of how short they are, always discharge the
lines before attaching any test lead. Because
of the possibly deadly consequences of
physical contact with such high-voltage
lines, engineers and technicians must always
treat electrical equipment and hookups as
though a lethal condition will eventually
occur. Therefore, no matter how unlikely it
may seem, never assume anything about the
safety of any test setup.
Ensure the safety of personal by checking
first-hand to eliminate all possible hazards!
Do Not Modify Test Equipment
Because of the added risk of introducing
additional or unknown
hazards, do not install
substitute parts or perform any unauthorized
modification to the Auto-Ohm. To ensure
that designed safety features are maintained, it
is recommended that all Auto-Ohm repairs be
performed at Vanguard Instruments Co. or by
an authorized repair-service. Unauthorized
equipment modifications can create unknown
safety hazards and will void the Auto-Ohm
warranty.
Follow Exact Operating Procedures
Any deviation from the operating procedures
described in this manual may create one or
more safety hazards, damage the unit or cause
test result errors; Vanguard Instruments Co.
assumes no liability for unsafe or improper
use of the Auto-Ohm.
