摘要
详细地叙述了利用 XF1b型交、直流精密电表校验装置采用直流补偿法检定低量值直流电流表示值误差时所存在的问题 ,并提出一种改进线路。同时 ,按照 JJF10 5 9— 1999《测量不确定度评定与表示》规范的要求对上述方法中所阐述的低量值直流电流表示值误差测量结果的不确定度进行了评定。
The problems existed during calibrating the error of indication of low magnitude DC amperemeter, using the DC compensation method on the model XF1b alternating current and direct current precise electric meter calbrating equipment, are narrated in detail and an improved circuit is advanced. At the same time, the uncertainty of the measurement result of the error of indication about low magnitude DC amperemeter in the above-mentioned according to the requirement of the JJF1059-1999 “Evaluation and Expression of Uncertainty in Measurement” is evaluated.
