7.4.1 Proof-tests
Emerson recommends the following proof-tests.
If you find an error in safety or functionality, you can document proof-test results and
corrective actions taken at Emerson.com/ReportFailure.
WARNING
Only allow qualified personnel to perform proof-tests.
Verify the Security switch is in the Unlock position during the proof-test and reposition it in
the Lock position after the proof-test.
7.4.2 Perform a guided proof-test
If you select the guided proof-test option, the Rosemount 3051 will support a feature that
can perform a guided partial or comprehensive proof-test.
This feature walks you through the necessary steps to perform a proof-test. The alarm
levels and required steps will be provided without the need to look them up.
To access the guided proof-test option:
Procedure
Go to Device Settings → Calibration → Proof Test → Perform Proof Tests.
The guided proof-test option comes with a proof-test log. This log stores the ten most
recent proof-tests directly in the transmitter. The log includes time stamp, communication
source, Pass/Fail result, and any user-defined notes.
