Trivia Quiz On Equipment And Calibration

In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Test your knowledge on this subject by answering our quiz.


Questions and Answers
  • 1. 
    Gage blocks are used to calibrate callipers and micrometres (among other things). They are made of metal or ceramic and must have very accurate lengths and very flat measurement surfaces. How do you check the flatness of a gage block?
    • A. 

      By holding it up to the light and sighting down the long edge

    • B. 

      By looking at it through an optical flat under polarized light 

    • C. 

      By feeling it with your hand

    • D. 

      With a measuring wand

  • 2. 
    There need to be defined procedures and schedules for carrying out checks needed to maintain confidence in the calibration status of…
    • A. 

      Reference standards

    • B. 

      Primary, working, and transfer standards

    • C. 

      Reference materials

    • D. 

      All of the above 

  • 3. 
    All the following are correct regarding calibrated equipment except:
    • A. 

      Can be labelled to indicate calibration status

    • B. 

      Can be coded to indicated calibration status

    • C. 

      Can be otherwise identified to indicate the status of the calibration

    • D.
