Instrumentation

Prepare a loop check

Keep the signal path, range, units and test evidence together before testing an analogue loop.

Preparation sequence

Identify the transmitter, isolator or splitter, input channel and HMI tag from approved records.
Record the signal type, engineering range, units and agreed acceptance criterion.
Assign the test owner and confirm the authorized procedure and safe test conditions.
Record actual readings and deviations; retain the approved evidence separately.
