DISSEMINATION OF THE UNIT OF MASS IN A FULLY AUTOMATIC MASS LABORATORY USING SUBDIVISION
Zoltán Zelenka
Abstract:
The Austrian Federal Office of Metrology and Surveying (BEV) has developed and realized in cooperation with Sartorius AG (Göttingen) and the Vienna University of Technology, three handling systems for automatic calibration of weights on high-precision mass comparators. The operation of these systems has an unusual aspect.
The robot covering the measuring range from 1 milligram up to 10 gram is a flexible tool to calibrate the majority of the weights. An analysis of this system shows that it has excellent repeatability, but also a systematic error. A modified weighing design is helpful to handle this property.
