CALIBRATION
4-25.
Introduction
4-26
The
8600A should
be
calibrated
every
6 months
or
whenever
repairs
have been
made,
to
insure
the
instrument
continues
to
operate
at its
rated
accuracy.
After
calibration
is
completed,
the
DC
current
performance
test,
paragraph
4-20
should
be
run
through
to
verify
the
functioning
and
accuracy
of the
current
dividers.
The
calibration
should
be
performed
under
the
following
environmental
conditons;
ambient
temperature
of
23°C
±5°C
and
a relative
humidity
of
less
than
80%.
Refer
to
Table
4-1
for
the
recommended
test
equipment.
Calibration
adjustment
locations
are
pictured
in
Figure
4-1.
Perform
the
follow-
ing
preliminary
steps
before
calibrating
the
instrument.
a.
Remove
the
instrument
from
the
case.
b.
Connect
the
8600A
to
the
appropriate
(1
1 5V
ac or
230V
ac)
line
power.
c.
Turn
the
instrument
on
and
allow
it to
warm-up
for
a
minimum
of
15
minutes.
d.
Insure
that
the
ac
and
dc
calibrators
are
up to
their
normal
operating
temperatures.
NOTE!
Use
only
non-metalic
adjustment
tools.

8600A is
presented
in
Table

Use
the
recommended
dc

to
apply
the
prescribed
dc
voltages
to the V-f2

terminals
and,
where
required,
make
the
adjustments
to
meet
the
specified
display
limits.
