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.
