4. From the Agua Clara Network (see directions over other computers if you do not see Agua Clara network)
   • Aguaclara> Agua Clara team folders> demo plant> Process controller> Methods> Base Setup
5. On the "configuration" tab, click on "edit rules" button in the lower right
6. Change the Residence Time and plant flow according to specifications of experiment
   • On the "Rules and States" tab, if the states list is blank, reload the base setup method file from step (4).

15. Insert a text file
    • "Plant Operation" tab, click on yellow square button that says "Text Log" on it
    • Insert text into log file (ex. "Start 100 ml/min Experiment, Run 1). Edit bolded sections appropriately.
16. Record test parameters, date, and time on table by computer.
