5.1.2.3.10 Memory management
These settings affect the hardware and thus the
SICAM Q80 7KG8080
unit must be connected for this purpose. There
are options for time-limited measurements and for a trial measurement.
Dialog for data storage settings
Storage location:
Selection of the storage medium. With
SICAM Q80 7KG8080, only
Compact Flash cards are used.
Measurement intervals:
Specification governing how long a measurement lasts before a new one starts. In this way,
for long-term monitoring measurements, new data sets are created cyclically which are capable of transfer to the PC,
and can be analyzed by it. This cyclical closing of the data files also provides increased data security.
Interval begins:
Specifies a time (hh:mm:ss) at which data acquisition is to conclude. All other termination times are
based on this time and on the interval duration.
Example:
Measurement intervals= 4 h, interval start = 12:00 PM
If measurement starts at 2:30 PM, the first interval end is at 4:00 PM; then at 8:00 PM, 12:00 AM, 4:00
AM, 8:00 AM...
Day of week:
The week intervals begin either immediately (
Measurement start
) or at a specified weekday.
Overwrite
oldest data if memory space exhausted:
To make room, the oldest data are deleted automatically when the data
carrier is full. Upon activating this option, the minimum size for
Storage memory for events
and Trigger is
automatically set to 0. This applies not only to the measurement task in progress but also to any existing
measurement data from previous measurement tasks.
Storage options for events and triggers:
This option lets you set sensible limits to the data volume resulting from
capture of trigger events.
With
Use available space
, triggered data are captured until the hard drive is full. Then, since there is no more
space for more data, data capture ends.
