3700 Portable Samplers
Section 3 Programming Guidelines
3-89
Example Time-Paced Samples at Nonuniform Intervals shows
how to program the sampler to take time-paced samples at non-
uniform time intervals. This example assumes the sampler is
configured for extended programming and that it connected to a
Liquid Level Actuator. The actuator will inhibit the sampler
until the liquid level rises to contact the actuator probe.
The sampler is to take 24 samples: the first samples are to occur
at 10-minute intervals for an hour, the next samples at
20-minute intervals for an hour, and the remaining samples at
30-minute intervals. One 500 ml sample is to be placed in each
bottle. Although this example assumes that nonuniform times
are being used with the actuator, uniform time intervals or flow
intervals can be used with the actuator as well.

The cycle of displays is repeated for each bottle until the sampling routine is done.

When the routine is completed, this message appears. It reports the status of the routine (“DONE”), the total number
of sample events, and the current time and date.
