CAUSE DESCRIPTION AND CORRECTIVE ACTIONS This is attributed to an oversight in data recording by the technician performing the test. Satisfactory test performance was indicated on data sheet checkoffs. Tests performed previous to and following the oversight indicate a satisfactory trip point setting. Other switches performing a redundant function were found with satisfactory test data. The importance of making sure all test data is complete was reviewed with testing personnel.

In the future two levels of review will be performed by the Instrument and Control department.
