適用范圍：This standard applies to direct acting indicating electrical measuring instruments having an analogue display, such as:- ammeters and voltmeters;- wattmeters and varmeters;- frequency meters of pointer and vibrating-reed types;- phasemeters, power-factor meters and synchroscopes;- ohmmeters, impedance meters and conductance meters;- multi-function instruments of the above types.It also applies to certain accessories used with these instruments, such as:- shunts;- series resistors and impedance elements.If other accessories are associated with instruments, this standard is applicable to the combination of the instrument and the accessory provided that the adjustments have been made for the combination.This standard also applies to a direct acting indicating electrical measuring instrument whose scale marks do not correspond directly to its electrical input quantity, provided that the relationship between them is known.This standard also applies to instruments and accessories having electronic devices in their measuring and/or auxiliary circuits.This standard does not apply to special purpose instruments which are covered by their own IEC standards.This standard does not apply to special purpose devices which are covered by their own IEC standards when they are used as accessories.This standard does not contain either requirements for protection against environmental conditions or the relevant tests. However, when necessary, and then only by agreement between the manufacturer and the user, tests to approximate the conditions of use may be selected from IEC 60068.This standard does not specify requirements concerning dimensions of instruments or accessories (for the former, see IEC 60473).
