Analisis Akurasi Timbangan Elektronik Secara Kalibrasi

Abstract

Calibration is defined as a series of activities that establish a relationship between the value indicated by a measuring instrument or measurement system (or the value represented by a material measure) and known reference values of the measured quantity, under specified conditions. The selection of a measuring instrument depends on the quantity to be measured, and balances are fundamental measuring instruments. Balances have long been used by humans in daily life, both for retail and wholesale trade, with the primary goal of determining the mass of an object. However, the data obtained from weighing is merely an estimate that contains a degree of doubt, known as uncertainty. This uncertainty reflects the reliability of a measurement result and is crucial in determining its quality. In laboratory or industrial settings, electronic balances are commonly used, often with very high resolutions, even down to micrometers. For mass calibration, a balance with an accuracy comparable to E1 class standard weights is required, aiming to minimize the resulting uncertainty. In conclusion, the OIML R 76-1 Standard plays a vital role in ensuring the accuracy and reliability of non-automatic weighing instruments. By adhering to the stipulated metrological and technical requirements, industries can ensure that their weighing equipment meets international standards and can be relied upon in various applications.
