HP 6268B Operating And Service Manual

two-part serial number. The first part is the serial number
prefix, a number-letter combination that denotes the date
of a significant design change and the country of manu¬
facture. The first two digits indicate the year (10 = 1970,
11 = 1971, etc.), the second two digits indicate the week,
and the letter "A” designates the U. S. A. as the country
of manufacture. The second part is the power supply serial
number. A different sequential number is assigned to each
power supply, starting with 001 01.
1-14 If the serial number on your instrument does not
agree with those on the title page of the manual. Change
Sheets supplied with the manual define the differences
between your instrument and the instrument described
by this manual.
1-15 ORDERING ADDITIONAL MANUALS
1-16 One manual is shipped with each power supply.
Additional manuals may be purchased from your local
Hewlett-Packard field office (see list at rear of this manual
for addresses). Specify the model number, serial number
prefix, and HP part number shown on the title page.
