Flash Memory Data Storage; Dsp Configuration - Arbiter Systems Power Sentinel 1133A Operation Manual

12.9 Flash Memory Data Storage

and definitions in IEC 61000-4-30, section 5.4, Supply–Voltage Dips and Swells. System Triggers are
1133A conditions that may be important to know, such as the 1133A losing GNSS synchronization
or the flash memory module being full. External triggers occur with a voltage changing state at any
of the four external event inputs. When a triggering condition is true, then an event can be logged
or some action taken. For additional information concerning Triggering in the DSP, see Chapter 8,
Working with Triggers and Downloading Event Records.

32 Mbytes (standard), number of records stored depends
on data items selected.
500, 64K blocks Registered data area (32 MB, standard)
Selectable from all functions measured and totalized by
1133A; each record is stored with a time tag
Selectable; default is as follows:
15 min. - Voltage, Current, Harmonics, Frequency
Variation
10 min. - Flicker
24 hours - IVDF
Power - other intervals as short as one minute may be
selected.
Event data stored upon occurrence
100,000 storage cycles, minimum
Indefinite; no power or battery required for data retention
