REPLACEABLE PARTS
Section VI
Paragraphs 6-l to 6-8
6-l. INTRODUCTION
6-2. This section contains information for ordering
replacement parts. Table 6-2 lists parts in alpha-
numerical order of their reference designators - and
indicates the description (see Table 6-l for abbrevi-
6-5. Replaceable Part Lists for Option001 are given
in Appendix. Changes were made in Assembly AlAl
and Assembly A5 only.
6-6. ORDERING INFORMATION
ations used) and HP part number of each part, to-
gether with any applicable notes.
6-7. To obtain replacement parts, address order or
inquiry to your local Hewlett-Packard Field Office
6-3. Miscellaneous parts associated with each as-
sembly are listed at the end of each assemblylisting.
Others are listed at the end of Table 6-2.
6-4. Exploded views of major parts of the instrument
are given in Figure 6-l through 6-8 to aid in identify-
ing mechanical parts.
The parts in these figures are
keyed to the mechanical parts index which are also
included in each figure.
(see lists at rear of this manual for addresses).
Identify parts by their Hewlett-Packardpart numbers.
6-8. To obtain a part that is not listed, include:
a. Instrument model number.
b. Instrument serial number
c. Description of the part.
d. Function and location of the part.
