To choose a Dampers pattern for the Pressure System

Valve Information
There are 2 Dampers you can control for the Pressure System experiment. You can specify the opening and closing of either of the two air-operated Dampers during an experiment

The dampers are air-operated Dampers that take a fraction of a second to go from fully open to fully clsed, and vice versa.


The Dampers will cycle close and open repeatedly during your experiment according to the parameters that you enter. You can specify the length of time that either Damper is closed and the length of time it is open.

For example: #1 closed for 15 seconds and open for 30 seconds will cause Damper #1 to cycle in 45 second periods (= 15 + 30) and be closed for 15 then open for 30 seconds.
