- Abstract:
- The results of the first comparison of laser distance measuring instruments (EDM) are reported. The test of the stability of the EDMs showed significant changes in the mean results in timescale months or even days. The uncertainty of the results mainly comes from the uncertainty of the reproducibility.
For the analysis both the deviations from the KCRV and the En numbers were calculated. For the evaluation of the reference value, the modified weighted mean approach has been chosen. Most results agreed within the claimed uncertainty. - Keywords:
