Agilent Technologies E4991A User manual

Caution
Do not exceed the operating input power, voltage, and current
level and signal type appropriate for the instrument being used, refer to
your instrument's Function Reference.
Electrostatic discharge(ESD) can damage the highly sensitive
microcircuits in your instrument. ESD damage is most likely to occur as
the test fixtures are being connected or disconnected. Protect them from
ESD damage by wearing a grounding strap that provides a high
resistance path to ground. Alternatively, ground yourself to discharge any
static charge built-up by touching the outer shell of any grounded
instrument chassis before touching the test port connectors.

Safety Summary
When you notice any of the unusual conditions listed below, immediately
terminate operation and disconnect the power cable.
Contact your local Agilent Technologies sales representative or
authorized service company for repair of the instrument. If you continue
to operate without repairing the instrument, there is a potential fire or
shock hazard for the operator.
- Instrument operates abnormally.
- Instrument emits abnormal noise, smell, smoke or a spark-like
light during operation.
- Instrument generates high temperature or electrical shock
during operation.
- Power cable, plug, or receptacle on instrument is damaged.
- Foreign substance or liquid has fallen into the instrument.

CLASS 1 LED PRODUCT
• 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
To avoid the danger of introducing additional hazards, do not install substitute parts or
perform unauthorized modifications to the instrument. Return the instrument to an
Agilent Technologies Sales and Service Office for service and repair to ensure that
safety features are maintained in operational condition.
• Dangerous Procedure Warnings
Warnings, such as the example below, precede potentially dangerous procedures
throughout this manual. Instructions contained in the warnings must be followed.
