Pengujian Anak Timbangan dengan Menggunakan Metode Kalibrasi untuk Menentukan Massa Konvensional

Abstract

This study aims to evaluate the performance of standard weights (anak timbangan) using the calibration method as a basis for determining the accuracy level of mass measurements. One of the key parameters in calibration is the conventional mass, which is the mass value obtained from measurements using traceable reference weights. The tested weight had a nominal mass of 100 grams and was calibrated by comparing it with a higher-class reference standard. The calibration result showed that the conventional mass of the tested weight (Unit Under Test/UUT) was 100.00019 grams. This value yields a deviation of +0.00019 grams or +0.19 milligrams from its nominal mass. When compared to the tolerance limit for a 100-gram F1 class weight, which is ±0,5 milligrams according to the OIML R 111-1 standard, the deviation remains well within the permissible range. This indicates that the weight meets the required accuracy standards and is considered suitable for use as a mass reference in measurement and calibration activitiesThe findings of this research demonstrate that the calibration method provides accurate information regarding the performance and reliability of standard weights and highlight the importance of considering conventional mass and tolerance limits in the testing of mass measuring instruments
