Weighing Scale Calibration: Practical Considerations and Tests • Weighing scales and instruments are used in various industries for various measurements. • Regular calibration is crucial to ensure accurate and correct measurements. • Calibration is often part of a legal or statutory verification program based on legislation. • Calibration is often based on a quality system, healthcare, traffic safety, or forensic investigation. • Regulations for weighing instruments and their calibration are provided by the European Institute of Standards and Technology (EISM). • The calibration process involves understanding the technical characteristics of the weighing instrument, the accuracy requirement, and what to do if calibration fails. • The calibration procedure should specify where to place the load during the test and document the locations. • The test load used in an eccentricity test should be at least one-third of the max load of the weighing instrument. • The eccentricity test is important to determine the difference caused by the location of the load, but it is not necessary to have an accurate calibrated load. • Regular calibration is crucial to ensure the proper functioning and accuracy of weighing instruments.
