Measurement uncertainty

Input a cause of uncertainty, for example : resolution
Check the distribution box, for example : uniform
Input the numerical data, several options are possible :
- the gaussian distribution is expressed as "+/-value" (k=2), so input value. For example : +/- 0.02 mm (k=2) the data to enter is 0.02
- the uniform distribution is expressed as "+/-value", so input value. For example : +/- 0.02 mm the data to enter is 0.02
- the uniform distribution is expressed as "value" so input value. For example : resolution=0.02 mm, the data to enter is 0.01
- the standard deviation is known, so input the value. For example : standard deviation=0.01 mm, the data to enter is 0.01
Click on the button Go. You get the combined standard measurement uncertainty and the expanded measurement uncertainty (k=2)
