- Abstract
To reduce the effect of environment factor against mass measurement of high accuracy, robot system with three-axis motion, data acquisition of environment parameters and function of remote communication is developed for realizing automatic remote measurement of high accurate weights. The system consists of function of automatic centering, combined weights to be load and unload, combined comparison measurement and function of automatic measuring for temperature, humidity and air pressure. Weights from 1 mg to 10 g are determined by the system with method of direct comparison and combined comparison. The experimental results show extended uncertainty of direct comparison and combined comparison from 1 mg to 10 g is better than 4.3 μg (k=2).
