(10) What is a Servo? - A mechanism set in motion by other mechanisms (10) What is Setpoint? - The desired outlet perssure (10) Which regulator is more accurate; pilot operated or direct operated? - Pilot operated (10) In which applications are pilot operated regulators normally employed other than servo regulation? - High capacity applications in commercial, institutional, and industrial settings. (10) How is the accuracy of a regulator determined? - The amount of flow it can pass for a given amount of droop determines the accuracy of a regulator. The closer the regulator is to setpoint, the more accurate it is. P2 - If the reading is 144 V what should you do? - Move the ground to the other terminal of the secondary and the reading between L1 and the ungrounded side of the secondary will read 96 V (10) What are the four factors that may affect droop? - Spring rate, diaphragm rate, orifice size, and inlet pressure (10) In many service and line pressure regulators how can you change the flow capacity? - By changing the orifice size (10) Which way should the adjustment screw be turned to increase downstream pressure? - Clockwise
