7.1.3.4. EDITING SAMPLE PERIOD AND REPORT PERIOD
The DAS defines two principal time periods by which sample readings are taken and
permanently recorded:

SAMPLE PERIOD:
Determines how often DAS temporarily records a sample
reading of the parameter in volatile memory.
SAMPLE PERIOD
is only used when
the DAS parameter’s sample mode is set for AVG, SDEV, MIN or MAX.

The
SAMPLE PERIOD
is set to one minute by default and generally cannot be
accessed from the standard DAS front panel menu, but is available via the
instruments communication ports by using APICOM or the analyzer’s standard
serial data protocol.

REPORT PERIOD
: Sets how often the sample readings stored in volatile memory
are processed, (e.g. average, minimum or maximum are calculated) and the results
stored permanently in the instruments Disk-on-Module (DOM) as well as transmitted
via the analyzer’s communication ports. The Report Period may be set from the
front panel. If the INST sample mode is selected the instrument stores and reports
an instantaneous reading of the selected parameter at the end of the chosen report
period.
Note
In AVG, SDEV, MIN or MAX sample modes
(see Section 7.1.3.3), the settings for
the Sample Period and the Report Period determine the number of data points
used each time the parameters are calculated, stored and reported to the COM
ports.
The actual sample readings are not stored past the end of the chosen report
period.
When the STORE NUM SAMPLES feature is turned on, the instrument will store
the number of measurements that were used to compute the AVG, SDEV, MIN or
MAX value but not the actual measurements themselves.
