Webb10 apr. 2024 · The process of calculating temperature uncertainty involves identifying and quantifying each source of uncertainty and combining them mathematically to produce an overall uncertainty value. The International Organization for Standardization (ISO) provides guidelines for calculating and reporting measurement uncertainty in ISO/IEC Guide 98-3. WebbThe overall uncertainty of the temperature measurement stems from three groups of uncertainty contributions: the uncertainty of the calibra- tion of the reference thermometer [11–13], the stability of the reference …

WebbIt is not possible to order a calibration where the calibration uncertainty must be less than e.g. 0.2%, since this depends of the meter performance. However, we often see that the uncertainty contribution of the meter is very small, and the calibration uncertainty is only 0.01-0.02% higher than the CMC value of the laboratory. WebbMeasurement at 99% confidence level = (50.42 ± 0.24) acre; Therefore, the uncertainty of the readings is 0.08 acre and the measurement can be represented as (50.42 ± 0.16) acre and (50.42 ± 0.24) acre at 95% and 99% confidence level. Explanation. The formula for uncertainty can be derived by using the following steps:
