By changing the standard output configuration, you can set up the Model 54e pH/ORP to perform a wide variety of control and monitoring tasks. The configuration procedures allow you to program the controller to meet the specific control and monitoring requirements of your particular plant. This is done by recording the desired configuration parameters on the List of Settings Form and then actually configuring them by using the keys on the controller front panel.
