Page 25: Chapter 4. Universal Pst
Introduction The Universal Parameter Setup Tool (Universal PST) is a Microsoft® Windows® application available from Woodward that enables you to adjust controller parameter settings and monitor controller operation. Universal PST also includes a graphical chart recorder that displays engine speed in real-time. This provides a visual representation of how the engine speed changes in response to changes in load, which can be very helpful when tuning the controller. -
