108 kinds of maintenance task the converter recognises: 40 convertible, 41 partly, 27 statutory. Each page names the condition that could replace the fixed interval, the reading that proves the check, how it is observed, whether the interval is set by law, and the evidence an ISO 55001 or ISO 45001 auditor accepts.
