To set the PID loop filter parameters from the Home screen, select CH X > Settings > PID Params and the screen in <imgref PID> will appear. The parameters for the PID loop filter are set in this popup screen. These parameters control the closed-loop behavior of the feedback. Each of these parameters will need to be tuned specifically for your plant. There is an option to enable or disable each parameter in the loop filter. There are a number of methods to tune a loop. We recommend the Ziegler-Nichols method.((A usable discussion of the Ziegler-Nichols method can be found here: http://faculty.mercer.edu/jenkins_he/documents/TuningforPIDControllers.pdf)) | To set the PID loop filter parameters from the Home screen, select CH X > Settings > PID Params and the screen in <imgref PID> will appear.
