7.1.5.4. Editing Sample Period and Report Period
The iDAS defines two principal time periods by which sample readings are taken and permanently recorded:
SAMPLE PERIOD: Determines how often iDAS temporarily records a sample reading of the parameter in
volatile memory. SAMPLE PERIOD is only used when the iDAS 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 iDAS 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-Chip 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 7.1.5 then press:
