AbolishedDirect acting indicating analogue electrical measuring instruments and their accessories--Part 7:Special requirements for multi-function instruments
直接作用模拟指示电测量仪表及其附件 第7部分:多功能仪表的特殊要求
Application Summary AI generated
This standard specifies the metrological and performance requirements for multi-function analogue electrical measuring instruments, such as those combining voltage, current, and frequency displays in a single unit. It is applied in the testing, calibration, and quality verification of panel-mounted or portable instruments used in industrial electrical systems, power distribution, and laboratory environments. The standard ensures accuracy and reliability when these instruments measure multiple electrical parameters simultaneously under defined conditions.
