Each event log record includes an event description, a time and date stamp, and additional
information on certain events.
For meters with batteries, all logged events are retained through a power outage. For meters
without batteries, the Event Log is periodically written to non-volatile memory. Events that
occur just prior to a power outage may be lost depending on whether they were backed-up
or not.
The contents of the event log can be viewed using the meter programming software.
The following events may be configured for recording in the D/T/L Register Event Log:
