CENTRON® Meter Technical Reference Guide 61
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 C12.19 C1SD/T/L register

Security Codes
Register security can be provided with primary, secondary, and tertiary security codes that
prevent unauthorized communication with CENTRON products. A Primary security code
allows complete access to the meter. A Secondary security code allows full read access with
limited write access to perform an automatic demand reset and to access the Alternate and
Test modes. A tertiary security code allows read-only access. For more information about
security codes, refer to the PC-PRO+ documentation.
