Calibration Steps
The calibration steps in an advanced setup are:
 Run Find Stops
or
1. Run Manual Find Stops.
2. Run Auto Tune.
3. View calibration parameters.
Run Find Stops
To determine valve position, the PST controller must measure and save the closed and open
positions of the valve. Do this automatically by running the Run Find Stops procedure.
The SVI II ESD first exhausts the actuator and measures the position, then fills the actuator
and measures the position. From these measurements the valve position is determined.
Correction can be made for nominal valve travel if it is less than full travel. A progress screen
appears while the find stops process is running. To run Find Stops:
1. Right-click and select Run Find Stops (Figure 328).
