Final element in a control loop is the? Correct answer-Control valve
What does an I/P transducer covert? Correct answer-The I/P transducer converts an electronic
signal, typically from a control system, to pneumatic signal used to control a valve
First thing to do after you Meg a motor is? Correct answer-Disconnect power or test megohmeter
What is a Megger Correct answer-the instrument used for measuring the resistance of the
insulation
Trending is the process of? Correct answer-A trend is the general direction taken during a specified
period of time..... Trend analysis is the process of looking at current trends in order to predict future
ones and is considered a form of comparative analysis
