本文以数字多用表校准装置为例,对其测得值的典型值进行不确定度分析,并针对实际工作中数字多用表校准后,整个测量范围内的测得值不确定度存在计算时间长、易出错、效率低等问题,提出预评估应用实际工作的思考.

文章主要分析了采用标准源法检定低阻抗小量程电压表(75 mV电压表)时存在的问题,提出了使用标准表检定方法,并分析使用该方法检定时的不确定度来源.分析结果表明,标准表法在检定低阻抗小量程电压表时,测量结果更可靠,更合理.

该文介绍了兼顾国防、军队现代化建设和经济社会发展的军民融合的发展路子,从国家战略部署的层面来看意义深远.

标准仪器设备的安全运输是实现计量保障的必要条件,正确、合理地进行仪器设备的移动和运输,能提升仪器设备的完好率,提高工作效率,降低成本,保证量值准确可靠,延长仪器设备的使用寿命.

Values can hardly be traceable for fixed-optics near infrared spectrometers at present.With an analysis on the structure and working principles of such spectrometers,we proposed principles of the specifications traceability,analyzed the specifications required being controlled by meterage,and put forward the cahbration methods for all specifications based on interference filters and neutral density filters as standard instrument Experimental results show that this proposal can realize metrological calibration of fixed-optics near infrared spectrometers,and solve the problem of traceability.
