Abstract:
Calibration of mass standards using manual mass comparators requires the repetitive loading and unloading of masses. The routine heavy-lifting could pose a threat to the integrity of the mass comparator and musculoskeletal health of the personnel. This study developed an automated rotary plate that served as an accessory for existing manual comparators in the laboratory. It is programmed to mimic the calibration process by alternately conveying the reference and test mass standards to and from the comparator. The results showed that the new calibration system can produce repeatability results that is up to 75% better than manufacturer’s declaration and 18% better than manual calibration. This demonstrates that the integration of the system enhances the repeatability of the manual mass comparators. This implies that the system can potentially be used to calibrate mass standards of even higher accuracy class than its intended application in the laboratory.
