Abstract
A method and arrangement keep track of the cumulative absolute drift of a measurement device, in connection with calibration actions performed by a calibrator. Measurement results are saved () in each measurement instant, and if they exceed a threshold value (), an adjustment step is performed (). Irrespective of the adjustment steps, the latest drift value () during the latest calibration interval is summed () with the previous cumulative drift value. The cumulative drift value, i.e. AbsDrift, is saved to a server, from where it can be illustrated visually (). If there is an uncommon pattern or large cumulative drift present, an indication or alarm () can be sent to the user of the calibrator.
