Reliability and maintainability design of the micro ammeter

Abstract The reliability design and maintainability design of the micro ammeter were made in the paper. Firstly, reliability and maintainability models for the micro ammeter were established, and corresponding predictions and allocations were made. Secondly, this paper developed an analysis tool to improve the efficiency of reliability calculations greatly. Then, three micro ammeters participated in the 612-hour reliability test, and all successfully passed the reliability assessment.
