This section contains information for ordering-
replacement parts.
Table 6-1 lists parts in alpha-
numerical order of their reference designators and
indicates the description and hp stock number of each
part, together with any applicable notes.
Table 6-2
lists parts in alpha-numerical order of their hp stock
number and provides the following information on
each part;
a. Description of the part (see list of abbreviations
below).
b. Typical manufacturer of the part in a five-digit
code; see list of manufacturers in Table 6-3.
c. Manufacturer's part number.
d. Total quantity used in the instrument (TQ column).
