Setting/changing damping time constant: DAMP key
Introduction
Damping time constant is a response time of the primary delay (65.2% response) for a step
response of the flow rate. When the output fluctuations are large increase the damping. A large
damping value stabilizes the output but lowers the response performance. The damping time
constant can be set to 0.5 up to 199.9 sec. using numeric keys.
Procedure
Use the following procedure to set the damping time constant.
