7.1.7. SAMPLE PERIOD AND REPORT PERIOD
The DAS defines two principal time periods by which sample readings are taken and
permanently recorded: Sample and Report periods.
 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 instrument’s
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 instrument’s Disk-on-
Module 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.
To define the REPORT PERIOD, follow the instruction shown in Section 7.1.4 then
