6700SR Refrigerated Sampler

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.

ming screens.

ming 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.
