Equipment
Required,
An
AC
Current
Source
capable
of
providing
currents
of 30
mA
(+
14%),
300
mA
(+
.14%)
and
1
A
(+
.24%)
at
a
frequency
between
100
Hz
and
20
KHz
is
required
for
the
follow-
1.
Set
the
AC
Current
source
for
an
output
of
30
mA
at
a
frequency
between
100
Hz
and
20
KHz
and
connect
it
to
the
HP
3457A
front
panel
I
and
LO
input
terminals.
2.
Set
the
HP
3457A
to
the
30
mA
range
and
the
number
of
digits
displayed
(DIGITS
DISP)
to
six.
4.
If
the
full-scale
readings
are
beyond
the
limits
specified
in
Table
4-6
and
on
the
Test
Record,
the
in-
strument
should
be
calibrated
or
repaired.
Refer
to
Section
V
of
this
manual
for
calibration
5.
Reduce
the
output
of
the
AC
Current
Source
and
disconnect
it
from
the
HP
3457A
input
terminals.
