Personnel involved in design, installation, operation, and maintenance

• On completion of the course, the student will be able to: Define calibration
• Recognize if an instrument is properly calibrated by  examining the instrument input and output
• Explain how calibration affects quality, productivity, and  safety
• Identify conditions when calibration is performed such as at  an installation, periodic scheduled maintenance, in response  to process deviation, and after repair or change in mounting  position
• Recognize accuracy and precision
• Identify zero shift, span error, combined zero shift and span  error, and non-linearity with a pattern of instrument readings  on an input/output graph or calibration data sheet
• Identify the basic elements of a calibration set-up
•  Identify the input values for a five-point
• Calibration check as a percent of the instrument’s range
