This display is used with samples-per-bottle multiplexing. The first line indicate the number of the upcoming sample
and the total number of samples each bottle is to receive. It also indicates the current bottle number. Thus, this
display indicates that the upcoming sample is the first of four samples and bottle one is to receive the next sample.
The second line indicates the scheduled time of the sample. The current time is shown in the right corner as the
sampler counts down to the next sample event time.
When the scheduled sample event time arrives, the second line will disappear while the sampler completes the
pre-sample purge.
When the pump begins to pump forward to deliver the sample, the second line will indicate the sample delivery by
displaying the word "PUMPING" and the sample volume being delivered. The message remains during the sample
delivery and post-sample purge.
When the sampling cycle is completed, the display will indicate the upcoming sample, shown here. This display
indicates that the upcoming sample is the second of four samples; the current sample bottle is bottle 1. The sample
event is scheduled for 6:15. The current time is just after 6:00.
The next displays illustrated here show the displays as the sample volumes are deposited in bottle 1.
