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 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 all personnel by
checking first-hand to eliminate every
possible hazard!
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 equipment. To ensure that
designed safety features are maintained, it is
recommended that all equipment 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 warranty.
Follow Exact Operating Procedures
Any deviation from operating procedures
described in this manual may create one or
more safety hazards, damage the unit, or
cause test errors; Vanguard Instruments Co.
assumes no liability for unsafe or improper
use of this equipment or for any collateral
damage to other equipment resulting from
such misuse.
