Sampling Method is the manner in which sampling is initiated. The V77 ADM-1
provides three Sampling Methods. These are Command (upon request via data
commands only), Immediate (upon exiting configuration), and Schedule (where
sampling begins at a specified time). The default Sampling Method is Command.
SAMPLE START TIME
Sample Start Time is the time sampling begins when Schedule Sampling Method is
selected. The start of sampling may be delayed up to twenty-four hours from the
current time recorded by the M Series time-of-day clock. The default Sample Start
Time is 00:00.
SAMPLE INTERVAL
You may program the V77 ADM-1 to sample continuously or in repetitive periods
where the V77 ADM-1 will sample for a certain period of time, stop sampling, and
then resume sampling after a specified time interval. Sample Interval is the time
between the start of sampling periods. The duration of a sampling period is
determined by the Sampling Rate and the Number of Samples to average. Continuous
sampling is selected by choosing no Sample Interval. The default Sample Interval is
00:00:00 (continuous sampling).
SAMPLE RATE
Sample Rate is the actual number of samples an V77 ADM-1 channel will read in one
second. Sample Rate may range from 1 to 4000 samples per second (S/sec). The
sample rate for an individual channel is the programmed rate divided by the number
of active channels.
The default Sample Rate is 1 S/sec.
NUMBER OF SAMPLES TO AVERAGE
The Number of Samples to Average is the number of samples averaged per data
message. The V77 ADM-1 will sample at a certain Sampling Rate and average a
specified number of samples. This average will then be quantized into a discrete
digital value and sent to a host module as a data message upon request or
automatically depending on the Reporting Method. The Number of Samples to
Average may range from 1 to 4000 samples. The default Number of Samples to
Average is 10 samples.
