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 is 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 is 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 DAS parameters are 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.
