- working memory (RAM): approx. 350,000 measurements
- internal backup memory, depending on the memory size that was ordered
- external CompactFlash card, depending on the memory size that was
ordered
The recorder saves the measurement data of the internal backup memory
automatically to the external CompactFlash memory card. Data storage
begins 3 minutes after insertion of the card.
The "CompactFlash card" menu provides additional functions for copying
data to the external memory card.
v Chapter 3.6 "CompactFlash card"
Different storage cycles, ranging from 125msec to 32767sec can be
configured for normal, event and timed operation under "group configuration".
The storage cycle determines the time interval for measurement storage.
Under this parameter, the value to be stored (average, minimum or maximum
value of the last storage period or instantaneous value) is configured
separately for normal, event and timed operation.
Data are recorded encoded in a proprietary, tamper-proof format.
The recording duration depends on various factors:
- number of analog and digital channels to be recorded
- storage cycle
- number of events in the event list
- number of reports running
