Paragraphs 1-11 to 1-14
1-11. INSTRUMENT IDENTIFICATION
1-12. Hewlett-Packard uses a two-section nine-
character (OOOOJOOOOO) or eight-character (000-00000
or OOOJOOOOO) serial number. The first three or four
digits (serial prefix) idenhfy a series of instrument;
the last five dig'its identify a particular instrument in
that series. A letter placed between the two sections
identifies the country where the mstrument was manu-
factured. The serial number appears on a plate located
on the rear panel. All correspondence with Hewlett-
Packard Sales/Service Offices with regard to an in-
strument should refer to the complete serial number.
1-13. MANUAL CHANGES
1-14. This manual provides operating and service
information for the HP Model4328A a portable instru-
Model 4328A
ment for measurement of low resistances. Informa-
tion in this manual applies directly to instruments (as
manufactured) with serial numbers prefixed by the
three digits indicated on the title page. If the serial
prefix of the instrument is above that on the htle page,
a "Manual Change" sheet supplied will describe
changes which Will adapt this manual to provide
correct coverage. Techmcal correction (if any) due
to known errors in print are called Errata and are
shown on the change sheet.. And if the serial prefix
or number of the instrument is below that on the title
page, see SECTION VU MANUAL CHANGES AND
OPTIONS. For information on manual coverage of
any HP instrument, contact the nearest HP Sales i
Service Office (addresses are listed at the rear of
this manual)
