5.6Programming Examples

The bay on the controller’s side accepts any of Teledyne Isco’s 700 Series Modules. These optional accessories are not required to operate the 6712FR. However, the modules offer an economical way to combine flow-rate or parameter monitoring with sam- pling.

The programming of these modules is integrated with the pro- gramming of the sampler, so attachment of a module will cause different screens to be displayed, depending on the type of module and the selections you make while programming.

Two modules that are commonly used are the 730 Bubbler Module, which monitors a flow stream’s level and flow rate, and the 750 Area Velocity Module for monitoring a flow stream’s level, velocity, and flow rate. Section 4 contains two examples of programming for modules. Module programming is the same in Extended as it was in Standard programming.

As an option, the 6712FR accepts up to 16 parameters from up to ten sensors with SDI-12 addresses from 0 - 9. The data param- eters used by the sonde and sampler must match. Certain vendors’ sondes, such as Hydrolab and YSI, have enhanced com- mands that facilitate “plug and play” setup. These Isco Ready sondes can tell the 6712FR what values they have, their order, and units of measure. Other sondes can be used, but require manual setup to identify proper data types for each data value reported.

For more information about programming SDI-12 sondes, refer to Section 6.

In addition to the features available with standard pro- gramming, and discussed in Section 4, extended programming offers:

•Nonuniform time pacing

•Random interval pacing

•Event pacing

•Multiple bottle compositing

•Time switched bottles or bottle sets

•Programmable sampler enable

•Pauses and resumes

•Two-part programming

•Automatic or user-defined suction head

•Suction line rinses

•Sampling retries

This manual provides several programming examples. Some, demonstrating simple tasks, appear in the margins. Others, dem- onstrating more complex tasks, appear as examples. Table 5-2on the following pages steps you through a storm water runoff sam- pling using extended programming.
