- Abstract:
- Manual mass comparison encumbers essentially a measurement or calibration with frequent interventions. Recently, an a5 automatic comparator (for the range of 1 mg ~ 5 g) from Mettler-Teledo (MT) has been introduced to Korea Research Institute of Standards and Science (KRISS) to ensure concretely the traceability of national standard. The stabilization time, the integration time and the number of measurements are selected as optimization parameters. The repeatability is obtained in more than 350 measurements. In the viewpoint of uncertainty, no preference condition is found from the result. The criterion to choose the stabilization time was proposed for 5 g weight range, and the time performance of a5 in legal metrology was commented.
