Safetv Precautions
The following
safety precautions should be observed before using the Model 3930A Multifunction
Synthesizer and any
associated instruments.
This instrument
is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety
precautions
required to avoid possible injury. Read over this manual carefully before using the instrument.
Exercise extreme caution when a shock hazard is present at the te.st circuit. The American National Standards Institute
(ANSI) states that a shock hazard exists when voltage levels greater than 30V nns or 4.2.4V peak are present. A good
safety practice is to expect that hazardous voltage is present in any unknown
circuit before measuring.
Inspect the connecting cables and test leads for possible wear, cracks, or breaks before each use.
For maximum
safety, do not touch the test cables or any instruments
while power is applied to the circuit under test.
Turn off the power and discharge any capacitors before connecting or disconnecting
cables from the instrument.
Do not touch any object which could provide a current path to the commc~n side of the circuit under test or power line
(earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of with-
standing the voltage being measured.
Instrumentation
and accessories should not be connected to humans.
