Display Configuration
This completes the function block configuration for a single pH input measurement. The next operation is
to build appropriate displays to interface with these blocks and provide the necessary instructions and entry
parameters to operate the function. The choice of operator displays and location on the display keys will
ultimately be the choice of the user, but an Overview display with the standardization entry parameters will
be needed as a minimum. The following displays and recipe are needed to support the application:
Enter a Startup Recipe with the following variables and values:
1 BUFFER Z 7.0 pH
1 BUFFER S 4.0 pH
1 TEMP 25.0 DEG C
1 MV ZERO 0.00 MV
1 MV SPAN -177.48 MV
