GENERAL INFORMATION
1-5. UMITS COVERED BY THIS OPERATION NOTE
Hewlett-Packard uses a two-part, nine character serial number which is stamped on the
serial number plate (see Figure 1-2 ) attached to the inside of the carrying case. The first
four digits and a letter are the prefix and the last five digits are the suffix of the serial num¬
ber. The letter in the serial number identifies the country where the instrument was man¬
ufactured. The prefix is same for all identical instruments, it changes only when a change is
made to the instrument. The suffix, however, is assigned sequentially and is different for
each instrument. This operation note applies to instruments with serial number prefixes
listed under Serial Numbers on the title page.
SERIAL NO.
Figure 1-2. Serial Number Plate
Units manufactured after this operation note was printed may have a serial number prefix
which is not listed on the title page. An unlisted serial number prefix indicates that the in¬
strument may be different from those described in this operation note. Operation notes for
new Instruments may be accompanied by a yellow Manual Changes supplement page, or
have a different part number. This supplement contains "Change information" explaining
how to adapt this operation note to newer instruments.
In addition to change information, the supplement may contain information for correcting
errors ( Errata) in previous operation notes. To keep this operation note as current and
accurate as possible, Hewlett-Packard recommends that you periodically request the latest
Manual Change supplements. The supplement for this operation note is identified by the
Print Date and Part Number, both of which appear on the operation note's title page.
For information concerning the serial number prefixes not listed on the title page or in the
Manual Change supplements, contact your nearest Hewlett-Packard Sales office.
