At the acceptance meeting, the expert group heard a report on the completion of the project, reviewed work reports, technical reports, intellectual property rights, etc. It was agreed that the project completed the research content stipulated in the contract and mission statement and agreed to pass the acceptance.

The project conducted in-depth research on the active compensation current ratio standard device and its automatic verification and calibration technology. The active current comparator and high-accuracy inductive shunt were developed. The method of traceability of the new current ratio standard was proposed and the automatic verification was developed. The calibration system realizes automatic measurement of the error of the current ratio standard.

The research results of the project have solved the problem of quick and efficient traceability of the current ratio standard, which can be extended to provincial-level measurement centers and gradually expand the scope of application of pilot sites, which has broad application prospects.
