A calibration indicates that the unit under test is withing manufactures specification. The equipment and procedure used has to be "good enough" (bad words in a cal lab) to have a high probability (nothing is 100%) of insuring the calibration documentation is valid. Things can can be a little looser if you are calibrating a 1% meter with a 10 ppm meter but it does not work the other way around.
