Performance
Tests
Introduction
This
section
provides the
test procedures
used to
verify that
the 4339B's
specications listed
in
Chapter
8,
General
Information,
of
this manual
are met.
All tests
can be
performed
without
access
to
the
interior
of
the
instrument. The
performance tests
can also
be used
to
perform
incoming
inspection,
and
to
verify
that
the 4339B
meets its
performance specications
after
troubleshooting
or
adjustment. If
the performance
tests indicate
that the
4339B
is
NOT
operating
within
the specied
limits,
check your
test setup
,
then
proceed
with
troubleshooting
if
necessary
.
Note
Allow
the
4339B
to
warm
up
for
at
least
30
minutes
before
you
execute
any
of
the
performance
tests
.
Note
Perform
all
performance
tests
in
ambient
conditions
of
23
C
6
5
C,
70%
RH.
Test
Equipment
T
able
9-1
lists
the
test
equipment
required
to
perform
the
tests
described
in
this
section.
Use
only
calibrated
test
instruments
when
performance
testing
the
4339B
.
Equipment
which
equals
or
surpasses
the
key
required
specications
of
the
recommended
equipment
may
be
used
as
a
substitute
.
Calculation
Sheet
The
calculation
sheet
is
used
as
an
aid
for
recording
raw
measurement
data,
and
for calculating
the
performance
test
results
.
The
performance
test
procedure
gives
the
test sequence
for performing
a test.
The
complete
set
of
measurement
data
is
recorded
on the
calculation sheet.
The results
are
calculated
using
the
equations
given
on
the
calculation sheet,
and the
results are
transcribed to
the
performance test
record.
The procedure
for using
the calculation
sheet is:
1. Photocopy the calculation sheet.
2. F
ollow the performance test procedure and record the measurement value(s), the 4339B's
reading,
etc., into the specied column on the calculation sheet.
3. Calculate
the test result using the appropriate equation given on the calculation sheet, and
record the test
result into the T
est Result column of the performance test record.
