About Stored Programs
After selecting a stored program,
review 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.

two sites — each requiring different
bottle 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.
6700 SAMPLERS
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 flowpaced
samples during the remainder of the event. With a twopart
program, you can set up part ‘A’ for the first-flush sample
and part ‘B’ for the remainder. Example 6 on page 31 shows a
storm-water sampling program.
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
program settings and any sampler enable conditions using rain
gauge data or YSI sonde parameters. These program settings
remain as long as you do not change the type of module, or
change the rain gauge or YSI Hardware Setup. If you make any
of these changes, 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 appears in quotations on the first line of the
main menu (See Example 4 on page 27).
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
PROGRAM 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
without losing the settings in your current program, select a
stored program 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.
