直接作用模拟指示电测量仪表及其附件 第6部分:欧姆表(阻抗表)和电导表的特殊要求

[中文适用范围]： IEC 60051的本部分适用于直接作用指示模拟电测量欧姆表（阻抗表）和电导表。本文件也适用于欧姆表（阻抗表）和电导表的一些不可互换附件。本文件也适用于直接作用指示电气测量仪器，其刻度标记不直接对应于其电气输入量，只要它们之间的关系已知。本文件还适用于其测量和/或辅助电路中的欧姆表（阻抗表）和电导表的电子设备。本文件不适用于绝缘欧姆表、接地欧姆表和外部商用功率欧姆表（阻抗表）和电导表。 [外文原描述]： IEC 60051-6:2017 applies to direct acting indicating analogue electrical measuring ohmmeters (impedance meters) and conductance meters. This document also applies to some non-interchangeable accessories of ohmmeters (impedance meters) and conductance meters. This fifth edition cancels and replaces the fourth edition published in 1984. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) updating of content in line with new editions of IEC 60051-1 and IEC 60051-9; b) addition of Annex A to specify the nonconformity classification of test items.
