Uji Kalibrasi Alat Ukur Massa pada Neraca Analitik Menggunakan Metode Perbandingan Langsung

The research describes the effect of weights on calibration results an analytical balance. This study aims to obtain uncertainty value balance test by comparison with standard E2 class weights. can be used determine feasibility measuring instrument tested through analysis performance scales based Limit Performance (LOP) parameter. method is a direct process carried out in this includes measurement repeatability readings, deviations from nominal indication, loading not at centre pan , and hysteresis. data deviation values, minimum correction hysteresis, uncertainty, LOP. show that reading power load ½ maximum capacity full 0.0042 grams. Deviations points 20, 40, 60, 80, 100, 120, 140, 160, 180, 200 grams have 0.04995 0.006378585 k=2.0 95% confidence level. In table LOP value, it known poor category, more advisable repair tool.
