List
of
Replaceable
Parts
5-1.
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.
5-3.
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.
c.
The ten-digit part
number
by which the item
is
identified at the John
Fluke
Mfg. Co. 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
PART NO column. If
a component
must 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 REF.
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.
5-4.

OBTAIN PARTS
