SAMPLE PERIOD is only used when the iDAS 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 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
In AVG, MIN or MAX sample modes, the settings for the SAMPLE PERIOD and the REPORT
PERIOD determine the number of data points used each time the average, minimum or maximum
is calculated, stored and reported to the COMM ports. The actual sample readings are not stored
past the end of the of the chosen REPORT PERIOD.
Also, the SAMPLE PERIOD and REPORT PERIOD intervals are synchronized to the beginning and
end of the appropriate interval of the instruments internal clock.
• If SAMPLE PERIOD were set for one minute the first reading would occur at the beginning
of the next full minute according to the instrument’s internal clock.
• If the REPORT PERIOD were set for of one hour the first report activity would occur at the
beginning of the next full hour according to the instrument’s internal clock.
EXAMPLE: Given the above settings, if iDAS were activated at 7:57:35 the first sample
would occur at 7:58 and the first report would be calculated at 8:00 consisting of data
points for 7:58. 7:59 and 8:00.
During the next hour (from 8:01 to 9:00) the instrument will take a sample reading every
minute and include 60 sample readings.
When the STORE NUM. SAMPLES feature is turned on the instrument will also store how many
sample readings were used for the AVG, MIN or MAX calculation but not the readings themselves.
REPORT PERIODS IN PROGRESS WHEN INSTRUMENT IS POWERED OFF
If the instrument is powered off in the middle of a REPORT PERIOD, the samples accumulated so
far during that period are lost. Once the instrument is turned back on, the iDAS restarts taking
samples and temporarily them in volatile memory as part of the REPORT PERIOD currently active
at the time of restart. At the end of this REPORT PERIOD only the sample readings taken since
the instrument was turned back on will be included in any AVG, MIN or MAX calculation. Also, the
STORE NUM. SAMPLES feature will report the number of sample readings taken since the
instrument was restarted.
