Calibration is more than simply placing reference masses on a weighing platform to assess the deviation between the indication and reference mass value.

Greifensee, Switzerland—November 28th, 2016—Metrological accuracy is critical to quality. Effective calibration of weighing instruments is the prerequisite for traceable and accurate weighing. To achieve this accuracy, an organization must have a thorough understanding of current metrological science—this includes a thorough understanding of calibration.
Calibration establishes a relationship between quantity values provided by measurement standards and corresponding indications, which is only complete if contributing measurement uncertainties are taken into account. For non-automatic weighing instruments, the only global definition of calibration is EURAMET calibration guideline cg-18, “Calibration of non-automatic weighing instruments”.
This white paper details the test procedures and measurement uncertainty estimation procedures laid out by EURAMET, highlighting laboratory and production applications. Minimum weight, which defines the lower boundary of the safe weighing range by scientifically defining the smallest sample quantity able to produce specified relative accuracy, is also addressed.
To learn more about how a thorough understanding of calibration and minimum weight can help ensure weighing tolerances are met in the lab, download “Measurement Uncertainty: Expert Know-How”.
Future installments of METTLER TOLEDO’s 2016 eCalendar will help further optimize lab processes for greater accuracy, so keep watching for additional information.
