6700SR Refrigerated Sampler

Storage For Extended Programs
The sampler stores five sampling programs: one standard and four
extended. Program storage eliminates the need to reprogram the
sampler with frequently used settings. This feature is especially
useful for complex extended programs such as two-part programs
or programs with many nonuniform-time settings.
Isco ships the sampler to you with factory programs that you can
modify to suit your own needs. All four extended programs are
identical to each other.
The stored programs will also save your 700 Series Module pro-
gram settings and any sampler enable conditions using rain gauge
data or YSI 600 Sonde parameters. These program settings remain
as long as you do not change the type of module, or change the rain
gauge or YSI 600 Hardware Setup. If you make any of these chang-
es, the sampler updates the stored programs to the current sampler
configuration.
Selecting a Stored Program
The sampler shows the extended programming screens, it always
has one current and three noncurrent programs, each occupying a
permanent location in memory. The first time you add the extended
screens, the current program is “EXTENDED 1,” one of the factory
extended programs. The name of the current extended program ap-
pears in quotations on the first line of the main menu (See
Exam-
ple 4 on page 25).
The factory programs are named “EXTENDED 1,” “EXTENDED
2,” “EXTENDED 3,” and “EXTENDED 4.” You can rename them
with more descriptive names, making them easier to identify. The
program name is one of the extended program’s settings.
The current program is the program you see when you select PRO-
GRAM from the start-up menu and page through the programming
screens. It is the program the sampler uses when you select RUN
from the start-up menu.
You cannot delete programs, but you can modify them as often as
necessary. However, to run a program with different settings with-
out losing the settings in your current program, select a stored pro-
gram and modify its settings.
To understand how this works, consider this example. You have
been running the current program, named “EXTENDED 1,” at site
A for several weeks. This program contains all the settings you
need for site A, and you don’t want to lose those settings.
Nevertheless, you need another program because you want to move
the sampler to site B, so you select “EXTENDED 2” and modify it
for site B. The settings in “EXTENDED 1” are preserved automat-
ically. When you return the sampler to site A, you won’t need to re-
program the sampler. Merely select “EXTENDED 1” again, double-
check the program settings, and run the program.
About Stored Programs
After selecting a stored program, re-
view the settings with the quick view
screens. Each sampling program
stores all the settings required by
the sampler to run a program.
These settings include the bottle-kit
information (number of bottles and
the bottle volume), the suction-line
length, the site description, start
times, and so on.
If you use the same program at two
sites — each requiring different bot-
tle configurations, suction line
lengths, or other details — always
check these settings before running
a program. You may need to make
minor changes to the program to
make sure the settings match your
equipment.
Stored Programs and
Reinitializing
Reinitializing the sampler restores
the program settings to the factory
settings shipped with the sampler.
Only reinitialize the sampler when
you can afford to lose the program
settings.
Note:
If the Bottle Full Detect setting is
critical to your sampling program,
always check this Hardware setting
after you select a different Extended
Program. See
Bottle Full Detect on
page 91.
