Instrument Serial Numbers

Agilent makes frequent improvements to its products enhancing performance,
usability, or reliability. Agilent service personnel have access to complete records
of design changes to each type of instrument, based on the instrument's serial
number and option designation.
Whenever you contact Agilent about your instrument, have the complete serial
number available. This will ensure that you obtain accurate service information.
A serial number label is attached to the rear of the instrument. This label has two
instrument identification entries: the first provides the identification number for
each option built into the instrument and the second provides the instrument's
serial number.
The serial number has two parts: the prefix (two letters and the first four numbers),
and the suffix (the last four numbers). Refer to
Figure 1-2.

The first two letters of the prefix identify the country in which the unit was
manufactured. The remaining four numbers of the prefix identify the date of the
last major design change incorporated in your instrument. The four digit suffix is a
sequential number and, coupled with the prefix, provides a unique identification
for each unit produced. Whenever you list the serial number or refer to it in
obtaining information about your instrument, be sure to use the complete number,
including the full prefix and the suffix.
