White Paper: Measuring Uncertainty – A New Software Function for Dynamic Display of the Uncertainty of Measurement

“Measuring Uncertainty” is a new QApp available in the Sartorius Cubis® II Pharma Package. This software function provides a dynamic display of the uncertainty of measurement, based on the EURAMET Calibration Guide No. 18 “Guidelines on the Calibration of Non-Automatic Weighing Instruments”1-3. 

“Measuring Uncertainty” is a global expanded function, given in the form of a straight-line equation and containing both a constant contribution and a contribution proportional to the reading. In most cases, this represents a sufficiently good estimation of the uncertainty of weighing results of the balance in use.   

Commonly Asked Questions:  

  • Why is the Measurement of Uncertainty Important?
      
    • High-performance lab balances are complex and sensitive devices. Many influences such as installation location and user expertise can influence displayed results. With a dynamic function displaying uncertainty for each measured value in the complete weighing range, users can print values with corresponding uncertainties. Required parameters can be easily set by Sartorius Service.
