Step 3 - Calibrate Travel
To determine valve position, the PST controller must measure the closed and open positions of
the valve. 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.
To calibrate PST controller travel:
 Click the Calibrate Travel checkbox (Figure 117).
