Measurement Uncertainty of the Weighing Instrument in Use
Stated is the expanded uncertainty with k=2 in use. The formula shall be used for the estimation of the uncertainty under consideration of
the errors of indication. The value R represents the net load indication in the unit of measure of the device.
Temperature coefficient for the evaluation of the measurement uncertainty in use:
Temperature range on site for the evaluation of the measurement uncertainty in use:
Linearization of Uncertainty Equation
Range
d
1 0.02 lb
To optimize the stability of the linearization, besides of the zero load only increasing measurement points with a test load of 5% of the
measurement range or larger are taken for the calculation of the linear equation.
