2 Instrument description
2.8 Data storage
Recording
- internal memory: approx. 350,000 measurements
capacity
- diskette: approx. 650,000 measurements
The recording capacity is reduced when many event messages are also
stored.
Storage rate
Different storage rates, ranging from 1sec to 32767sec, can be configured for
normal, event and timed operation under "configuration".
The storage rate determines the time intervals at which the measurements are
stored.
Stored value
Under this parameter, the value to be stored (average, instantaneous, mini-
mum, maximum or peak value) is configured separately for normal, event and
timed operation.
Recording
The data are recorded encoded in a proprietary format.
format
Recording
The recording duration depends on various factors:
duration
- number of analog channels and event traces being recorded
- storage rate
- number of events in the event list

Optimization
The recording duration can be optimized by process-oriented selection of the
of recording
storage rate.
duration
In normal operation (no fault, no alarm, ...), a storage interval as long as possi-
ble (e.g. 60sec, 180sec, ...) should be selected, depending on the specific ap-
plication.
In the event of an alarm or a fault, the storage rate can be shortened via event
operation, which ensures that the measurement data are recorded with a high
time resolution.
