Understanding Diagnostics
This section explains the diagnostics feature available in the iOLM
application.
Diagnostics are used to provide additional information about detected
problems or ambiguous measurement situations, such as root cause
possibilities for the fail status of a link element. The diagnostics provide
help to troubleshoot faulty connectors, understand why link elements are
tagged as fail or unknown, indicate unexpected instrument or test
conditions and so forth.
Link elements with an associated diagnostic are marked with an
icon,
and the diagnostics are displayed in the Link View and Elements tabs.
More than one diagnostic can be associated with any given element.
Elements diagnostics are associated with specific link elements issues.
Each failed link element will have associated diagnostics to assist in
troubleshooting. Some elements, such as macrobends, will have
associated diagnostics even with a pass status.
