Abstract The uncertainty of measurements associated with the following correction methods: advanced correction of additive linear drift, correction of additive and multiplicative effects, as well as joint correction of a linear drift and systematic additive and multiplicative effects is analyzed in the present article. For each correction method sensitivity coefficients and amplitude responses according to which noise and internal and external interferences influence the corrected measurement result have been determined. Besides uncertainty of reference quantities, the main factors which limit the efficiency of correction are: non-linearity of measurement function including non-linearity of ADC, no idealities of the switching systems and external and internal noises and periodic interferences. The efficiency of correction of systematic additive and multiplicative effects was studied for the multifunction 16 bit PCI DAQ of family NI 6250.

测量链系统效应自动校正的有效性

摘要 本文分析了与以下校正方法相关的测量不确定度：加性线性漂移的高级校正，加性和乘性效应的校正，以及线性漂移和系统加性和乘性效应的联合校正。对于每种校正方法，根据噪声和内部和外部干扰影响校正测量结果的灵敏度系数和幅度响应已经确定。除了参考量的不确定性之外，限制校正效率的主要因素是：测量函数的非线性，包括ADC的非线性、开关系统的不理想性以及外部和内部噪声和周期性干扰。
