you want to start the routine with another bottle, enter the starting bottle number.
This display appears as the sampler counts down the time remaining to the start time. The first line reports the bottle
which will receive the next sample volume. The second line reports the start time at the left and the current time on
the right.
When the start time arrives, the sampler will take the first sample. The sample event cycle begins with a pre-sample
purge. During the purge, the display indicates the number of the bottle that will receive the sample volume.
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
number of the bottle that is to receive the sample at the upcoming sample event. The left side of the second line
displays the scheduled time for the next event. The current time is displayed on the right side.
The cycle of displays, shown in Steps 12 through 13, 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.
