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 COMM 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.

To define the REPORT PERIOD, follow the instruction shown in Section 7.1.3 then press:
