Caution: When the profile log is filled to maximum capacity of unread records, the
oldest unread records start being overwritten one day at a time. Set the log
interval and number of channels so that the maximum number of log
capacity days between readings is not exceeded. It is important to read the
meter before the log becomes full to prevent loss of unread data.
