Abstract: In order to solve the problem of analyzing the metering characteristics of special test equipment and improve the effectiveness of metrological traceability,from the perspective of equipment users,based on the test ability,the system analysis method is applied to form the analysis method of metrological characteristics,including method train of thought,identification range,“metrological” principle,analysis steps and result expression,etc.Finally,taking the muzzle shock wave test system as an example,the application of the analysis method is described.The results show that this method is simple and feasible,which can not only provide support for the re-evaluation of metering characteristics of in-service equipment,but also provide a reference for the demonstration of new(or in-research) equipment.
