This part of IEC 60051<\/span> <\/span> applies to direct acting indicating phase meters, power factor meters and synchroscopes having an analogue display.<\/p>\n

This document also applies to non-interchangeable accessories (as defined in 3.1.23 of IEC 60051\u20111:2016<\/span> <\/span>) used with phase meters, power factor meters and synchroscopes.<\/p>\n

This document also applies to a phase meter or power factor meter whose scale marks do not correspond directly to its electrical input quantity, provided that the relationship between them is known.<\/p>\n
