Changing to and from Extended and Standard Screens
The sampler is shipped so that the standard programming screens
appear when you first turn the sampler on. The start-up screen
tells you which programming screens the sampler is currently us-
ing. After the extended programming screens are added, the sam-
pler continues to display them (even if the sampler is turned off)
until they are replaced by the standard programming screens.

One-Part and Two-Part Programs
Extended programming lets you set up a “one-part” program or a
“two-part” program. One-part programs let you fill
all bottles of the
tub with one set of pacing, distribution, and enable settings. Two-
part programs add an additional set of extended pacing, distribu-
tion, and enable screens to the sampling program. Each set of
screens is called a program part. The program parts are simply
called part ‘A’ and part ‘B.’ Both parts share the program settings
for suction-line length, suction head, and rinses and retries. They
also share one start-time setting.
Each part has its own group of bottles. Because settings for each
part are independent of each other, the sampler, when running a
two-part program, fills each bottle group as if they were being filled
by two different programs. Two-part programs finish when both
parts are done.
Two-part programming is ideal for sampling storm events. Many
storm-water run-off monitoring permits require a first-flush grab
sample within the first 30 minutes of the storm event and flow-
paced samples during the remainder of the event. With a two-part
program, you can set up part ‘A’ for the first-flush sample and part
‘B’ for the remainder.
Example 6 on page 29 shows a storm-water
sampling program.
