A serial number label is attached to the power sensor. The serial number has two 
parts: the prefix (two letters and the first four numbers), and the suffix (the last four 
numbers). Refer to the Example Serial Number shown in Figure 1-1.

The two letters identify the country in which the unit was manufactured. "US" 
represents the USA and "MY" represents Malaysia. The four numbers of the prefix 
are a code identifying the date of a major design change incorporated in your power 
sensor. The four digit suffix is a sequential number and, coupled with the prefix, 
provides a unique identification for each unit produced. 
When seeking information about your power sensor refer to the complete serial 
number and include the full prefix number and the suffix number.
