INITIAL INSPECTION
2-4.
Inspect
the
shipping
container
for
damage.
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
checked mechanically
and
electrically.
The
con-
tents
of
the
shipment
should
be
as shown
in
Figure
1-1.
Procedures for checking electrical
performance are given in
Section
IV.
If
the
instrument
does
not
pass the electrical perfor-
mance
tests, refer to the adjustments
in
Section
V
of
this manual.
If
a circuit
malfunction
is sus-
pected, refer to troubleshooting information
in
Section VIII.
If
the
instrument
does
not
pass the
above electrical tests,
or
if
the
shipment
contents
are
incomplete,
or
if
there
is
mechanical
damage
or
defect, notify the nearest Hewlett-
Packard
office.
If
the
shipping
container
is
damaged,
or
the
cushioning
material shows
signs
of
stress, notify the carrier as well as the
Hewlett-Packard
office.
Keep
the
shipping
materials for carrier's inspection.
The
HP
office
will arrange for
repair
or
replacement without
waiting for claim
settlement

the Power Line
Module
on
the
rear
panel
of
the

Select
the line voltage
and
fuse as follows:
a.
Measure
the ac line voltage.
b. Refer to Figure
2-1.
At
the
instrument
rear
panel
power line module, select the line
voltage
(100,
120,
220,
or
240 volts) closest to
the voltage you measured
in
step
a.
Note
the available line voltage must be within
+5%
or
-10%
of
the line voltage selection
as shown in Table
2-1.
If
it is not, you
must
use
an
autotransformer
between the power
source
and
