Example: Time-Paced Samples at Nonuniform Intervals (Continued)
When the start time occurs, the sampler will take the first sample. The sample event cycle begins with a pre-sample
purge. During the purge, the display indicates the receiving bottle number.
As soon as the pump runs forward to deliver the sample volume, the message on the second line appears. This
message remains through the post-sample purge.
This display appears when the post-sample purge from the previous sample event is completed. It indicates the bottle
number which is to receive the sample at the upcoming sample event. The second line displays the scheduled time
for the next event on the left; the current time is displayed on the right.
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.

Nonuniform times can be entered in either the method shown in
Example Time-Paced Samples at Nonuniform Intervals, or by
specifying a clock time and date for each sample. On the fol-
lowing page, Example Time-Paced Samples at Nonuniform Clock
Times shows the displays used to enter the clock times. The type
of display, clock time or minutes, used in the program sequence is
controlled by the settings in the Nonuniform Times configure
option; you must specify either clock time or minutes in that con-
figure option.
