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.
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.
of parts belonging to and grouped by individual as-
semblies; the latter consists of all parts not im-
mediately associated with an assembly.
