Facts regarding measurement -
•Can you ever measure the true value of
something?
−No, there will always be errors
•How important is this fact?
−Very important, as measurement is never complete
unless you know how good it is!
• How is this taken into account in today’s
calibration & metrology?
−By applying & documenting the measurement uncertainty
process to the tests being done
