Robotic mass measurement system, which used automatic measurement and data processing, has become the trend of the high accuracy mass measurements. In international comparison and mass-related scientific research, automatic measurement system together with ABABAB weighing cycles can reduce or eliminate the linear drift greatly and improve the accuracy of measurement results further. In this paper, three linear drift error elimination methods of ABABAB weighing cycle model were analyzed, and the corresponding mathematical expressions of error calculation were given, then experimental data was analyzed and compared. All of these three methods based on ABABAB weighing cycle can be applied for automatic measurement in the future.
