LIST OF
REPLACEABLE
PARTS
5-1.
INTRODUCTION
5-2. This
section of the
manual contains a
listing of
replaceable
components for this
instrument.
The first
listing
contains a
complete
breakdown of all
the major
assemblies
followed
by
subsequent
listings that
itemize
the
components on
each major assembly.
An
illus-
tration
accompanies each
major assembly
listing to aid
in
locating the
listed
components.
5-3. Assemblies
and
subassemblies are
identified by
a
reference
designation beginning
with the
letter A fol-
lowed by
a number
(e.g..,
A1
etc.).
Electrical
components
appearing
on the
schematic diagram
are identified by
their schematic
diagram
reference designation.
Compo-
nents not appearing
on the
schematic diagram
are con-
secutively
numbered throughout
the parts list.
These
components are
identified with whole
numbers on
the
arrow
call-out illustrations
and
by
index
numbers on the
grid illustrations.
Flagnotes are
used throughout
the parts
list and refer
to special ordering
explanations
that are lo-
cated in
close proximity to the
flagnotes.
5-4. COLUMN DESCRIPTION
a.
The REF
DESIG column
indexes the
item descrip-
tion
to the
associated illustration. In
general the
reference designations are
listed under each
assembly
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
INDEX NO.
column lists
coordinates which
locate
the designated
part
on
the
associated grid
illustrations.
c.
The
DESCRIPTION column
describes
the salient
characteristics of
the component.
Indention of the
description indicates
the relationship to
other
assem-
blies, components,
etc.
In
many
cases it is
necessary
to abbreviate in this
column. For
abbreviations and
symbols used,
see the following
page.
d.
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 order-
ing
parts from the factory or
authorized representa-
tives.
e.
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.
f. 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.
g.
The
TOT QTY column
lists the total quantity of the
items
used
in
the
instrument and reflects the latest
Use Code.
Second and
subsequent listings of the
same item
are referenced to the first
listing with the
abbreviation REF.
In the case of optional
subassem-
blies, plug ins,
etc. that are not always
part of the
instrument, or are deviations from
the basic instru-
ment model, the TOT
QTY column lists the total
quantity
of
the item in that particular
assembly.
h. 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 mainten-
ance for one year
or more at an isolated site,
it
is
recommended
that at least one of every
part
in the
instrument be
stocked. In the case of optional sub-
assemblies, plug-ins,
etc. that are not always part
of the instrument, or are
deviations from the basic
instrument model, the REC QTY
column lists the
recommended
quantity
of
the item in that particular
assembly.
i.
The USE CODE
column identifies certain parts
which have been added,
deleted or modified during
the
production
of
the instrument. Each part for
which a Use Code has
been assigned may be iden-
tified with a particular
instrument serial number
