7.4.3. 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. 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. SAMPLE PERIOD is only
used when the DAS parameter’s sample mode is set for AVG, MIN or MAX.
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 7.4 then
