nitial Inspection
Your 3468A was carefully inspected before it left the factory. It should be free of
mars or scratches and in proper working order upon receipt. You should, however,
inspect the instrument for any damage
that may have occurred
in transit.
If the
shipping container or cushioning material is damaged,
it should
be kept until the
contents of the shipment have been checked for completeness and the instrument
has been mechanically and electrically inspected. Procedures for checking the elec-
trical performance of the 3468A are given in the 3468A
SERVICE MANUAL
(-hp-
part number
03468-90001).
If there is any mechanical
damage or the contents
are incomplete, or the instrument does not pass its performance tests, notify the
nearest
Hewlett-Packard
office
(a list of the -hp- Sales
and
Service
Offices
is
located
in the back of this manual).
If the shipping container is damaged,
or the
cushioning
material
shows
signs
of stress,
notify
the carrier
as well
as the
Hewlett-Packard
office. Save the shipping materials for the carrier.
Preparation for Use

Line Voltage Selection
Refer to the rear panel of the 3468A
