Hewlett-Packard makes frequent improvements to its products to enhance their performance,
usability, or reliability. HP service personnel have access to complete records of design changes
to each type of equipment, based on the equipment’s serial number. Whenever you contact
HP about your analyzer, have the complete serial number available to ensure obtaining the
most complete and accurate information possible.
The serial number label is attached to the rear of the analyzer. The serial number has two
parts: the prefix (the first four numbers and a letter), and the suffix (the last five numbers).
See Figure l-l.
The first four numbers of the prefix are a code identifying the date of the last major design
change incorporated in your analyzer. The letter identifies the country in which the unit
was manufactured. The five-digit suffix is a sequential number and is different for each
unit. Whenever you list the serial number or refer to it in obtaining information about your
analyzer, be sure to use the complete number, including the full prefix and the suffix.
