6-4. MECHANICAL AND CHASSIS PART LOCATIONS AND REFERENCE DESIGNATIONS
Most mechanical parts are identified in Figures 6-1 to 6-9. These figures are located at the end of
this section. Major mechanical parts have reference designations that begin with the letters MP. To
find the part number and description of a mechanical part, find the part in one of the photographs
or
drawings, and then look up the reference designation in Table 6-3. Mechanical hardware, such as
screws, are listed under the part which they attach. For example, the screws that attach the fan (Bl)
to the rear panel are listed under
B1.
6-5. RECOMMENDED SPARES LIST
Stocking spare parts for an instrument is often done to ensure quick return to service after a malfunction
occurs. Hewlett-Packard has prepared a "Recommended Spares" list for this instrument. The contents
of the list are based on failure reports and repair data. Quantities given are for one year of parts
support. You can request a complimentary copy of the "Recommended Spares" list from your nearest
Hewlett-Packard office.
When stocking parts to support more than one instrument
or to
support a variety of Hewlett-Packard
instruments,
it
may be more economical to work from one consolidated list rather than simply
adding together stocking quantities from the individual instrument lists. Hewlett-Packard will prepare
consolidated "Recommended Spares" lists for any number
or
combination of instruments. Contact your
nearest Hewlett-Packard office for details.
