| 摘 要： | 在直流电流表的检定或校准中,通常采用标准直流电流源输出标准电流,被检电流表的读数与标准直流电流源的数值进行比较。电流测量仪表的分辨力对重复性测量有一定影响,而且分辨力对测量结果的不确定度有影响。通过测量实例说明,如何在直流电流表的测量结果中考虑分辨力的影响。

| Abstract: | When using the direct-current ammeter to perform the verification or calibration, it is usually to use the standard direct-current generator for output the standard direct-current and then comparing the readings of the tested ammeter and standard DC generator. The resolution of the current measurement device has some effect on the repetitive measurement and the important effect on the uncertainty of the measurement result. The paper is to use the measure example to illustrate how to consider the resolution effect in the measurement result of the direct-current ammeter |
