    Hi,
    I have a question in relation with the accuracy of a measurement equipment. I have a scale, type: QA65EDE-D.
    Weighing capacity: 64 kg.                                                         Readability: 1g.                                                                     Repeatability (standard deviation): =< +-2g.                           Linearity: =< +-2g. 
    From these datas how can I calculate the accuracy of the equipment? For example I simple have to add the standard deviation and linearity failure or I have to use a different way of calculating? In this case the failure is less than +-4g at every value?
    Thanks,
    Regards,
    Máriusz Ódor.

    Dear Mariusz Odor,
    You cannot get accuracy (bias) from any of the data you have stated.
    If you have Minitab, there is a function under Stat>>Quality Tools>>Gage Study>>Linearty and Bias that will provide the answer you seek.
