Instrument Identification
Agilent instruments are identified by a two part, ten-digit serial number. The
serial number is located on the instrument's rear panel between the rear
terminals and fan filter. The number is in the form 0000A00000. The first
four digits, called the serial number prefix, is the same for all identical
instruments. It changes only when a change is made to the instrument. The
letter indicates the country of origin (A indicates the instrument was built in
the United States of America). The last five digits, called the serial number
suffix, are unique for each instrument.
Be sure to include the entire serial number, both prefix and suffix, in any
correspondence about your instrument.
