Example Sampling with Stops and Resumes shows how to
program the sampler to take time-paced samples at uniform time
intervals of 15 minutes starting at 6:00 a.m. on the following day.
One 500 ml sample is to be placed in each bottle. The sampling is
to continue from 6:00 a.m. until 8:00 a.m.. The sampling will
resume again at 11:00 a.m. and continue until 1:30 p.m.. It will
pause until 4:00 p.m. and continue again until 6:00 p.m.. When
the sampling stops at 6:00 p.m., fewer than 24 samples may have
been taken. Note that the Sampling Stop and Resumes configure
option has settings that allow you to take a sample at the stop
and resume times. See the section Sampling Stop/Resume.
