Sensors Covered by Manual
These sensors have a two- part serial number: the prefix (two letters and the
first four numbers), and the suffix (the last four numbers). The two letters
identify the country in which the unit was manufactured. The four numbers
of the prefix are a code identifying the date of the last major design change
incorporated in your sensor. The four- digit suffix is a sequential number
and, coupled with the prefix, provides a unique identification for each unit
produced. The contents of this manual apply directly to all serial numbers
unless otherwise indicated.
