Servicing
Connector Care and Cleaning Precautions
Remove the power cord to the instrument. To clean the connectors use
alcohol in a well ventilated area. Allow all residual alcohol moisture to
evaporate, and fumes to dissipate prior to energizing the instrument.
Danger of explosion if battery is incorrectly replaced. Replace only with
the same or equivalent type recommended. Discard used batteries
according to manufacturer’s instructions.
These servicing instructions are for use by qualified personnel only. To
avoid electrical shock, do not perform any servicing unless you are
qualified to do so.
The opening of covers or removal of parts is likely to expose the user to
dangerous voltages. Disconnect the instrument from all voltage sources
before opening.
No operator serviceable parts inside. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers.
The detachable power cord is the instrument disconnecting device. It
disconnects the mains circuits from the mains supply before other parts
of the instrument. The front panel switch is only a standby switch and is
not a LINE switch (disconnecting device).
The power cord is connected to internal capacitors that may remain live
for 5 seconds after disconnecting the plug from its power supply.
To prevent electrical shock, disconnect the Keysight Technologies
U3047AM08 from mains electrical supply before cleaning. Use a dry cloth
or one slightly dampened with water to clean the external case parts. Do
not attempt to clean internally.
If flammable cleaning materials are used, the material shall not be
stored, or left open in the area of the equipment. Adequate ventilation
shall be assured to prevent the combustion of fumes, or vapors.
