8.Printer

9.Reports/History

Note

If you choose NOT MEASURED for any selection, the flow meter will make no further reference to that value or function for the rest of the program, and you will not be able to activate that process or function later on unless you reprogram step 1. If there is a feature or option you need that does not appear on your display when the manual says it should, return to step 1 and make sure you have not inadvertently left it turned off in either the Program or Setup menus.

Note that selecting some features automatically excludes oth- ers. For example, selection of pH or D. O. excludes the other parameter, unless you use the YSI 600 Multi-Parameter Sonde, which measures pH, D.O., and conductivity at the same time.

Step 1, Operating Mode, determines how you set up the flow meter. In this step there are two choices, Program and Setup. Program advances you to step 2, and from there on you cor- relate the flow meter to the flow stream. Setup selects various basic “housekeeping” features for the flow meter. Here you determine the internal clock, site identification, measurement setup, hysteresis, report contents, operation of the display back- light, and program lock. In Program you select the units of measure the flow meter will use for the display, calculations, and reports.

This method keeps program size manageable and makes pro- gramming more efficient. By turning off unneeded features of the program early, you do not have to keep de-selecting those fea- tures over and over as you work through the program.

Consequently, you should choose carefully from the first step. We suggest you study the program first, then fill out the Pro- gramming Worksheets (in the back of this manual), and program the flow meter last, if you are unfamiliar with the unit.
