Documentation
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.
