GENERAL PRECAUTIONS
The following are general precautions that are not related to any specific pro-
cedure and, therefore, do not appear elsewhere in this publication. These are
precautions that personnel must understand and apply during various phases
of instrument operation or service.
Potentially lethal voltages are present in this instrument. Serious shock haz-
ards from voltages above 70 volts may exist in any connector, chassis, or cir-
cuit board. Observe the following precautions:
• Use the buddy system any time work involving active high voltage components is
required. Turn OFF the power before making/breaking any electrical connection.
Regard any exposed connector, terminal board, or circuit board as a possible shock
hazard. DO NOT replace any component or module with power applied.
• If test conditions to live equipment are required, ground the test equipment
before probing the voltage or signal to be tested.
• Personnel working with or near high voltage should be familiar with modem
methods ofresuscitation.
• DO NOT wear jewelry (rings, bracelets, metal watches, and/or neck chains)
while working on exposed equipment. Be very cautious about using hand tools
near exposed backplanes, bus bars, and/or power supply terminals. Use properly
insulated tools. When making test connections to the power supply terminals and
bus bars; use only insulated probe tips.
• Verify that the instrument is set to match the available line voltage and the correct
fuse is installed.
• DO NOT install substitute parts or perform any unauthorized modification to this
