Instrument Identification

The power supply is identified by a unique, two-part serial number, such as, US37450101. The items in this serial number are explained as follows:

US37450101 The first two letters indicate the country of manufacture. US = United States.

The next four digits are the year and week of manufacture or last significant design change. Add 1960 to the first two digits to determine the year. For example, 37=1997. The third and fourth digits specify the week of the year (45 = the forty-fifth week).

The last four digits (0101) are a unique sequential number assigned to each unit.
