The procedure is described in chapter
the DIGSI Help.
Parameter: Flash-Memory Size
•
Default setting (_:10081:161) Flash-memory size = 1500 MB
With the Flash-memory size parameter, you specify a maximum memory size of the slow-scan recorder
on the mass storage.
If the flash memory becomes full while recording new fault records, the device automatically deletes the
oldest file to be able to continue recording (ring buffer).
The maximum number of storable fault records is limited by the set flash-memory size and the size of the indi-
vidual fault records.
NOTE
i
i
If you change the capacity of the recorder or delete a recorder instance, the flash memory of the device is
re-organized and all recordings of the device – not just those of the changed recorder – are automatically
and irrevocably deleted.
Before this, save your recordings by exporting them manually in DIGSI 5 or archiving them in SICAM PQS.
Then, delete your recordings in DIGSI 5 to avoid inconsistencies between new and old recordings.

The setting aid Estimated record size is dimmed and thus, you cannot set or change it.
Keep in mind that the estimation refers to typical sinusoidal signals and that the size of a fault record can
increase in the event of distorted signals.
