3.24.3.2 Length of record
The recording capability is about 7.4 years when one quantity is recorded and
the demand interval is set to 180 minutes. The recording time scales down
proportionally when a shorter demand time is selected or more quantities are
recorded. The recording lengths in days with different settings used are presented

If the data source for the selected quantity is removed, for example, with
Application Configuration in PCM600, the load profile recorder stops
recording it and the previously collected data are cleared.
