- Abstract:
- The teaching of metrology in undergraduate courses includes concepts such as traceability, calibration and uncertainty. This paper proposes a certain activity that students will have to realize in the Metrology Laboratory. The purpose of this activity is that students understand the contribution that the traceability chain has in the estimation of the uncertainty of a measurement. The activity should be realized in three stages. The first one consists of the construction of a mass measuring device. In the second stage, the pupil realizes the calibration of the device with two different patron mass kits. In the third stage, the student weighs different problem masses and informs the value of the measurand with an uncertainty statement, calculated with the information of his previous calibrations. Once the student has obtained different uncertainties of the same measurand, estimated with the same instrument, the instruments’ traceability relevance will be set.
