Position Settling Time
The Position Settling Time field is used to select the waiting time between each step. The
settling time must provide sufficient delay between steps to allow stabilization. Generally
larger valves should have a longer settling time than small ones to accurately observe their
behavior. If the settling time is set too short, it can adversely affect the performance
calculations.
Control Signal
This graph shows all of the signals relative to time on the x axis during the test.
HDR
This graph shows the calculated hysteresis + deadband and repeatability values over the
command.
