Knowing the drift of a caliper, one might be able to determine the right frequency calibration that should be attributed to it. However, when trying to learn about the order of such a drift, opinion is divided on the question. Some metrologists say that the caliper does not drift while others claim to have established a periodicity according to an observed drift. From real calibrations of over a hundred calipers, this study tries to prove the drift or not of calipers in use in the industrial world.
