| 摘 要： | 检定规程指出,为了便于数据处理,仪表的检定数据一般用格数表示。判断该表是否合格,不仅要看各次测量示值与实际值之间的最大基本误差,还要看其实际值之间的最大变差。只有两项最大误差均小于该仪表规定的误差限,所检定的仪表才算合格。通过实例,阐述了由于操作失误给检测结果造成测量误差,分析仪表超差的原因所在。

| Abstract: | To determine whether or not a power meter is considered acceptable depends both on the maximum intrinsic errors between the indication of each measuring and the actual indications and on the maximum variation rate between the actual indications.Only when the above errors are less than the rated errors can the tested meter be acceptable.Through the practical examples,the article expatiates on measurement errors caused by incorrect operation.In addition,the reasons for the meter ultra errors are also analyzed. |
