Warninit
Before turning on the instrument,
you
must connect the protective earth
termina:, of the instrument
to
the
protective earth conductor of the (mains)
power cord. The mains plug
must
only be
inserted in a socket outlet with
a
protective earth contact.
Do
not negate
the protective action by using an
extension power cord without a
protecti,ve grounding conductor.
Grounding one conductor of a
two
-
conductor outlet is not sufficient
protection.
Service instructions are for trained
service :personnel.
?b
avoid dangerous
electric shock, do not perform any
service unless qualified
to
do
so.
Do
not
attempt internal service
or
aaustment
unless another person, capable of
rendering first aid and resuscitation,
is
present.
If
you energize this instrument using an
auto
-
transformer (for voltage reduction)
make sure that the common terminal is
connected
to
the earth terminal of the
power s~urce.
Whenever it is likely that the ground
protectitm is impaired, you must make
the instrument inoperative and secure it
against .anyunintended operation.
Do
not operate the instrument in the
presence of flammable gases
or
fumes.
Operation of any electrical instrument in
such an environment constitutes a
definite safety hazard.
Do
not install substitute parts
or
perform
any unauthorized modification
to
the
instrument.
Capacitors inside the instrument may
retain a charge even if the instrument is
disconnected from its source of supply.

Only one parameter can be active at
a
time, although two may be
visible on the display. The active parameter
is

a
parameter.
If
you hold two neighbouring keys down, the auto

at
a
rate of three times the lower digit.

carry operates when you change
a
digit from

Leading zeroes are not displayed, but the vernier keys can
still be used to increase/decrease the “digit”. If you try to adjust a
parameter outside its valid range, you
will
see
an
error message telling
you the parameter limit.

Initial Inspection
Inspect the shipping container for damage. If the container
or
cushioning material
is
damaged, keep
it
until the contents of the
shipment have bleen checked for completeness and the instrument
has
been verified both mechanically and electrically.
To
avoid hazardouselectric shock, do not perform electrical
tests
when there are signs
of
shipping damage to any part
of
the
instrument’souter covers or panels.
Warning
9
If
the contents are incomplete,
or
there
is
mechanical damage,
or
if
the instrument does not
pass
the Performance Tests in Chapter
3,
notify the nearest Hewlett-Packard office. Keep the shipping materials
for inspection
by
the carrier. The HP office
will
arrange for repair or
replacement without awaiting settlement.
