適用范圍：This standard applies to direct acting recording electrical measuring instruments for direct and alternating electrical quantities, which are used for recording the varying values of one or more measured quantities as a function of time. It applies to strip, drum and disk recording instruments, viz:— ammeters;— voltmeters;— single-phase and polyphase wattmeters, varmeters, phasemeters and power-factor * meters (active or reactive);— frequency meters;— ohmmeters.It applies to multirange and multipurpose instruments of the above types.It applies to such instruments which incorporate rectifiers or diodes or thermocouples in their measuring circuits.It also applies to certain accessories used with such apparatus, viz.:— shunts;— series resistors and impedances.Where other accessories are associated with instruments inasmuch as the calibration has been made of the instrument together with the accessory, the standard is applicable to the combination of instrument and accessory.This standard also applies to electrically operated measuring equipment provided that the electrically operated measuring recording instrument (receiver) only is considered, and that the relationship between the non-electrical quantity and the electrical one is known.It also applies to recording instruments, t
