Parts

INTRODUCTION
5-2.
This
section contains
complete descriptions
of
those parts one might normally expect
to
replace during
the
life
of
the instrument.
The
first listing is
a
break-
down
of
all of
the
major assemblies
in the
instrument.
Subsequent
listings
itemize
the
components
in
each
as-
sembly.
Every
listing
where
possible,
is
accompanied
by an illustration
identifying
each component
in
the
listing.
Assemblies
and subassemblies are
identified
by a
reference
designation beginning with the letter A,
(e.g.
,
Al, A2, A3,
etc.).
Components
are
identified
by
the
schematic diagram
reference designation
(e.g.
HI, C107, DS1). Flagnotes are used throughout
the
parts
list
and
refer
to
ordering
explanations.
The
flag-
note explanations are located
at
the end
of the
parts
list
section
in
which
they appear.

COLUMNAR
INFORMATION
a.
The
REF
DESIG column indexes
the
item description
to the associated
illustration. In
general the refer-
ence designations are
listed in
alpha-numeric order.
Subassemblies
of
minor
proportions
are
sometimes
listed
with
the
assembly
of
which
they are a part.
In
this case,
the
reference designations for the
components
of the
subassembly
may
appear out
of
order.
b.
The
DESCRIPTION
column
describes the salient
characteristics
of
the
component.
Indention of the
item description
indicates the relationship to
other
assemblies, components,
etc.
In
many
cases
it
is
necessary
to
abbreviate
in this
column.
For
ab-
breviations
and symbols
used, see
Appendix
B.

The
ten-digit part
number
by which
the
item
is
identified
at
the
John Fluke

is
listed
in
the
STOCK NO
column.
Use
this
number when
ordering parts from
the
factory or authorized rep-
resentatives.
d.
The Federal Supply Code
for the
item manufacturer
is listed in the
MFR
column. An
abbreviated
list
of
Federal Supply
Codes
is
included
in the
Appendix.
e.
The
part
number which uniquely
identifies
the item
to
the original manufacturer
is
listed
in the
MFR

column.
If
a

be
ordered
by description,
the
type
number
is listed.
f.
The
TOT
QTY
column
lists the total quantity
of the
item used
in
the
instrument.
Second and subsequent
listing of
the
same
item are referenced
to the
first
listing
with the abbreviation

In the
case
of
optional
subassemblies,
plug
ins, etc.
that
are not
always part
of the
instrument, the
TOT QTY
column
lists
the
total
quantity of
the item
in chat particular
assembly.
g.
Entries
in
the
REC QTY
column
indicate the
recom-
mended number
of
spare
parts
necessary
to
support
one
to five
instruments
for
a period
of
two
years.
This
list
presumes
an
availability of
common
elec-
tronic
parts at the maintenance
site.
For
mainte-
nance
for
one year or
more
at
an
isolated
site,
it
is
recommended
that at least one
of
every
part
in
the
instrument
be stocked.
h.
The USE
CODE
column
identifies certain parts
which have been added, deleted or modified through-
out the
life of
the
instrument. Each
part for
which
a
Use Code has been assigned
may
be identified with
a particular instrument
serial
number
by consulting
the
Serial
Number
effectivity
List,
paragraph
5-7.
As Use Codes
are
added
to the
list,
the
TOT QTY
column
listings
are
changed
to reflect the
most
current information.
Sometimes when
a part
is
changed, the
new
part
can and
should be used
as
a
replacement for the
original part. In
this
event
a
parenthetical
note
is
added
in
the
DESCRIPTION
column.
