Luxon Software Logotype, Assistant 2.3, The program for using to analyze the uncertainty of measurement results of any physical quantities.

 

 

Description of the Assistant's interface

 
Graphical user interface of Assistant is based on five windows – if we insert required data then the current window hides and next window appears.

1.      The user inserts project title, project description in the first window “Project Description”.

2.      The user insert mathematical model of uncertainty using Assistant equation editor in the second window “Mathematical model”. He defines also all quantities included in the mathematical model.

3.      The user gives available numerical data about the input quantities in the third window “Input data”. He inserts here: observations in case of quantities determined using A method, distribution type and other parameters necessary to determine the standard deviation of quantities determined using B method.

4.      Assistant presents results of calculations of correlation coefficients between quantities determined using the A method in the fourth window “Correlation”. The default value of the correlation coefficients between other input quantities is zero. However, the user can set by any other values within the range from –1 to 1.

5.      Fifth window “Results” is used for presentation of calculation results of the combined standard uncertainty and the expanded uncertainty of the output quantity.

Calculation results of the combined standard uncertainty are presented in form of uncertainty budget table. This table presents a list of all input quantities, estimates of the input quantities, the standard uncertainties, types of probability distributions of these quantities, the sensitivity coefficients, and the uncertainty contributions of all the input quantities. Additional table presents results of calculation of the expanded uncertainty of the output quantity. 

In spite presented above scientific terminology even persons with very basic metrological education can quickly master Assistant and use it efficiently in their field of applications.
