Configuration
Once all electrical connections are made, a very specific function block and display interface configuration
is needed to properly standardize and view the pH measurements. The specific elements of the
configuration for a single measurement are described in Figure 75. Additional measurements would
require duplicating the elements for each sensor to be measured. The copy and paste feature of the Control
Builder software provides a convenient method for this duplication.
