Calibration of Weights and Weight Sets Based on Micro-Mass Standard Measurement System

摘要

The growing and evolving dynamics in mass and force measurements has inevitably necessitated the need for high precision and accurate results. As a result, measurements in micro-gram(s) and nano-Newtons levels have increasingly attracted potential research interests. In an effort to develop such solutions, the National Institute of Metrology (NIM) has set up a new robot system CCR10 (readability 0.1 μg) for accurate measurements of weight(s) (≤ 1 mg). This system is based on computer controls and linear-drive trains, and is used for calibration/verification of weight(s) below 10 g. A detailed description of the robot's metrological parameters and calibration results thereof is presented in the current paper.
