3700 Portable Samplers
Section 3 Programming Guidelines
with the run-state displays that appear while that routine is
being executed. You can use the run-state displays to monitor the
sampler's progress through a routine.
Examples Time-Paced Sequential Sampling through Time-Paced
Composite Sampling illustrate the basic programming sequence.
Because many of the features of the extended programming
mode are affected by selections made in the configure sequence,
examples for the extended programming sequence follow the
section Foreign Languages and Metric Units of Measure. We rec-
ommend you become familiar with the basic programming mode
procedure and examples before using the extended programming
mode. Most of the procedures used in the extended programming
mode duplicate those of the basic mode and are not repeated in
the extended programming procedures section.
Flow charts accompany examples for both programming modes.
These charts diagram the program sequence structure for each
mode. Figure 3-8 charts the Basic Programming Mode structure.
Figures 3-10, 3-11, and 3-12 chart the structure of the Extended
Programming Mode. The charts are provided to act as a "map" to
the programming process. Both charts are divided into sections
— Sample Pacing, Sample Distribution, Sample Volume, and Key
Times — which correspond to the steps listed in the procedure
discussed below. Each chart contains the input displays used in
the sequence. The input displays on each chart are labeled with
their display number so they can be cross-referenced with the
listing found in Appendix D.
As noted earlier, Teledyne Isco ships the sampler with a test
program and factory configuration settings. The examples in this
manual assume that you are using all factory settings, and that
the sampler will use the 24-bottle base and a 10-foot length of
3
/
-inch vinyl suction line. The settings with which your 3700 is
8
shipped include the size of bottle ordered and the size, type, and
length of suction line. When you check the configuration settings,
be sure the settings match your equipment, not the example.
Most program and configure settings can be reinitialized to
factory settings, if desired. Table 3-4 lists the factory settings.
The Run Diagnostics section discusses the reinitialize option.
