Instruments and Calibration
This is an instructor led, competency based program designed for master level electricians. The course will teach electricians to understand the operation and maintenance of DC drives. The course covers in detail the operation of and understanding of analog and digital drives. The student will be introduced to Drive Fundamentals for analog and digital drives. The student will apply a DC drive to an application.
- Learning Objectives:
- Given a process description the student will design and draw a Piping and Instrument drawing.
- Given a variable transformer, calibration meter, and graph paper the student will be able to calibrate a meter, determine its non-linearity, and plot a calibration point.
- Given a number of instruments data sheets the student will be able to determine if the instrument is a primary standard, secondary standard, or working standard.
- Given an instruments reading taken over a period of thirty days and the process upper and lower control limits the student will be able to calculate the Test Uncertainty Ratio of the system.
- The student will be able to construct a calibration graph for a pressure sensor using a 2 o 20 Ma panel meter, pressure sensor and power supply.
- The student will be able to calibrate a 4 to 20 ma valve positioner and a panel meter to read position. The student will produce a graph of measured milliamps verses position.
- Given a computer and display screen the student will be able to generate, transmit and display a message on the screen.
- The student will be able to construct a HART system and transmit data from a field device to a computer system.
- The student will be given fail systems and must find and correct the problem within 15 minutes time.
