General Safety Precautions
The following general safety precautions must be observed
during all phases of operation, service, and repair of this
instrument. Failure to comply with these precautions or with
specific WARNINGS elsewhere in this manual may impair the
protection provided by the equipment. Such noncompliance
would also violate safety standards of design, manufacture,
and intended use of the instrument. Keysight Technologies
assumes no liability for the customer’s failure to comply
with these precautions.
• Ground the Instrument
To avoid electric shock, the instrument chassis and
cabinet must be grounded with the supplied power cable’s
grounding prong.
• DO NOT Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of
inflammable gasses or fumes. Operation of any electrical
instrument in such an environment clearly constitutes a
safety hazard.
• Keep Away from Live Circuits
Operators must not remove instrument covers. Component
replacement and internal adjustments must be made by
qualified maintenance personnel. Do not replace
components with the power cable connected. Under
certain conditions, dangerous voltage levels may remain
even after the power cable has been disconnected. To
avoid injuries, always disconnect the power and discharge
circuits before touching them.
• DO NOT Service or Adjust the Instrument Alone
Do not attempt internal service or adjustment unless
another person, capable of rendering first aid and
resuscitation, is present.
• DO NOT Substitute Parts or Modify the Instrument
