标准摘要
[中文适用范围]： 适用于用于测量电压和电流的 Xt 记录仪，可测量和记录作为时间函数的模拟电量。对于其他电量的测量，IEC 51的相关部分也适用。也适用 [外文原描述]： Applies to X-t recorders used for the measurement of voltage and current which measure and record analogue electrical quantities as a function of time. Also applies to non-interchangeable accessories and accessories of limited interchangeability (e.g. shunts, impedance-elements) if they are used with the recorder and the adjustments have been made for the combination. IEC 61143-1 and IEC 61143-2 cancel and replace IEC 60484 (1974).
