the shipping
con-
tainer
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
anJ electrically checked. Procedures for testing electric^
performance of the 3455A
are given
in
Section IV.
If
the
contents are incomplete, if there is mechanical damage or
defect, or if the multimeter
does
not
pass
the
Performance
Tests,
notify the nearest
Hewlett-Packard Office. (A list
of
the -hp- Sales
and
