SECTION VI
REPLACEABLE PARTS
6-1 INTRODUCTION
6-2 This section contains information for ordering
replacement parts. Table 6-4
lists
parts
in
alpha¬
numeric order
by
reference designators and provides
the following information:
a. Reference Designators. Refer to Table 6-1.
b. Description. Refer to Table 6-2 for ab¬
breviations.
c. Total Quantity (TQ). Given only the first
time the part number is listed except in instruments
containing many sub-modular assemblies, in which
case the TQ appears the first time the part number
is listed in each assembly.
d. Manufacturer's Part Number or Type.
e. Manufacturer's Federal Supply Code Num¬
ber. Refer to Table 6-3 for manufacturer's name and
address.
f. Hewlett-Packard Part Number.
g. Recommended Spare Parts Quantity (RS)
for complete maintenance of one instrument during
one year of isolated service.
h. Parts not identified by a reference desig¬
nator are listed at the end of Table 6-4 under Me¬
chanical and/or Miscellaneous. The former consists
of parts belonging to and grouped by individual as¬
semblies; the latter consists of all parts not im¬
mediately associated with an assembly.
6-3 ORDERING INFORMATION
6-4 To order a replacement part, address order or
inquiry to your local Hewlett-Packard sales office
(see lists at rear of this manual for addresses).
Specify the following information for each part:
Model, complete serial number, and any Option or
special modification (J) numbers of the instrument;
Hewlett-Packard part number; circuit reference des¬
ignator; and description. To order a part not listed
in Table 6-4, give a complete description of the
part, its. function, and its location.
