SAFETY
SUMMARY
The
following
general
safety
precautions
must
be
observed
during
all
phases
of
operation
of
this
instrument.
Failure
to
comply
with
these
precautions
or
with
specific
warnings
elsewhere
in
this
manual
violates
safety
standards
of
design,
manufacture,
and
intended
use
of
the
instrument.
Hewlett-Packard
Company
assumes
no
liability
for
the
user’s
failure
to
comply
with
these
requirements.
BEFORE
APPOTNG
POWER
Verify
that
the
instrument
is
set
to
match
the
available
line
voltage.
GROUND
THE
INSTRUMENT
This
product
is
a
Safety
Class
1
instrument
(provided
with
a
protective
earth
terminal).
To
minimize
shock
hazard,
the
instrument
chassis
and
cover
must
be
connected
to
an
electrical
ground.
The
instrument
must
be
connected
to
the
ac
power
mains
through
a
three-conductor
power
cable,
with
the
third
wire
firmly
connected
to
an
electrical
ground
(safety
ground)
at
the
power
outlet.
Any
interruption
of
the
protective
(grounding)
conductor
or
disconnection
of
the
protective
earth
terminal
will
cause
a
potential
shock
hazard
that
could
result
in
personal
injury.
If
the
instrument
is
to
be
energized
via
an
external
autotransformer
for
voltage
reduction,
be
certain
that
the
autotransformer
common
terminal
is
connected
to
the
neutral
(earth
pole)
of
the
ac
power
lines
(supply
mains).
FUSES
Only
fuses
with
the
required
rated
current,
voltage,
and
specified
type
(normal
blow,
time
delay,
etc.)
should
be
used.
Do
not
use
repaired
fuses
or
short-circuited
fuseholders.
To
do
so
could
cause
a
shock
or
fire
hazard.
DO
NOT
OPERATE
IN
AN
EXPIOSIVE
ATMOSPHERE
Do
not
operate
the
instrument
in
the
presence
of
flammable
gases
or
fumes.
DO
NOT
REMOVE
THE
INSTUMENT
COVER
Operating
personnel
must
not
remove
instrument
covers.
Component
replacement
and
internal
adjustments
must
be
made
only
by
qualified
service
personnel.
DO
NOT
EXCEED
INPUT
RATINGS
This
instrument
may
be
equipped
with
a
line
filter
to
reduce
electromagnetic
interference
and
must
be
connected
to
a
properly
grounded
receptacle
to
minimize
electric
shock
hazard.
Operation
at
line
voltages
or
frequencies
in
excess
of
those
stated
on
the
line
rating
label
may
cause
leakage
currents
in
excess
of
5.0
mA
peak.

supply
Analog
Programming
The
power
supply
has
an
analog
port
for
remote
programming.
The
output
voltage
and/or
current
of
the
power
supply
may
be
controlled
by
d-c
programming
voltages
applied
to
this
port.
The
port
also
provides
a
monitor
output
that
supplies
a
d-c
voltage
proportional
to
the
output
current.

General
Information
Accessories
Output
Characteristic
General
The
power
supply
can
operate
in
either
CV
(constant
voltage)
or
CC
(constant
current)
over
its
voltage
and
current
ratings
(see
“Performance
Specifications”).
The
operating
locus
is
shown
by
the
Output
Characteristic
Curve
in
“Supplemental
Characteristics”.
The
operating
point
is
determined
by
the
voltage
setting
(Vg),
the
current
setting
(Is),
and
the
load
impedance.
Two
operating
points
are
shown.
Point
1
is
defined
by
the
load
line
cutting
the
operating
locus
in
the
constant-voltage
region.
This
region
defines
the
CV
mode.
Point
2
is
defined
by
the
load
line
cutting
the
operating
locus
in
the
constant-current
region.
This
region
defines
the
CC
mode.
Downprogramming
The
power
supply
can
sink
current
for
more
rapid
down
programming
in
the
CV
mode.
For
Series
654xA
and
655xA
supplies,
this
capability
is
defined
by
the
second
quadrant
area
(-!«)
of
the
Output
Characteristic
Curve.
These
supplies
can
sink
about
20%
of
their
maximum
rated
positive
output
current.
For
Series
657xA
,
this
is
an
uncharacterized
current-sinking
area
that
provides
a
limited
downprogramming
capability.
