Although the clock in the electricity meter is set at manufacturing, the user
(utility) must ensure that the SET CLOCK command (ECS70) is sent to the
meter as soon as possible after registration, and certainly before the first
time-based command is sent. Until this command is successfully completed,
the meter will record unsynchronized data.

The security log has only 100 entries. After this, it will overwrite the oldest
item (i.e., it is a circular buffer). The user (utility) must read the security log
frequently enough to prevent the loss of data.
It is advised that the user (utility) ensures that they use appropriate checks on
the data they receive from the meters to ensure that messages/responses are
consistent with the expected data. For example, responses should correlate
with commands which were known to have been sent, and the meter
cumulative registers should never go backward (i.e., reduce).
