IEC 61083-3:2020 pdf download.Instruments and software used for measurement in high-voltage and high‑current tests
1 Scope
This part of IEC 61083 is applicable to digital recording instruments used for measurements during tests with high alternating and direct voltages and currents. It specifies the measuring characteristics and calibrations required to meet the measuring uncertainties and procedures specified in the relevant IEC standards (e.g. IEC 60060-1, IEC 60060-2, IEC 60060-3, IEC 62475, IEC 61180). This document is applicable to those digital recording instruments that will be designed and type tested according to this document. This document  defines performance requirements for digital recording instruments used during tests with alternating voltages and currents (AC) or direct voltages and currents (DC); specifies the necessary requirements for such instruments to ensure their suitability for use under the relevant standards;establishes the tests and procedures necessary to demonstrate their compliance; defines the terms related to digital recording instruments with recording function and access to raw data. NOTE Examples of relevant alternating and direct voltages and currents to be measured are listed in Annex D. This International Standard has the status of a horizontal standard in accordance with IEC Guide 108.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: IEC Electropedia: available at http://www.electropedia.org/ ISO Online browsing platform: available at http://www.iso.org/obp 3.1 Digital recording instruments 3.1.1 approved instrument measuring device that is shown to comply with the requirements set out in IEC 61083-3 3.1.2 digital recording instrument device with digital output capability of the recorded input Note 1 to entry: This definition includes digital recorders, digital oscilloscopes, digital peak voltmeters and other digital recording instruments if applicable. Note 2 to entry: The waveform of the digital record is usually displayed on a screen, plotted or printed. This process may change the appearance of the waveform due to the processing involved. 3.1.3 assigned measurement range range of input voltage for which the digital recording instrument can be used within the uncertainty limits given in IEC 61083-3 3.1.4 output displayed (in any way) value of a digital recording instrument at a specific instant or the numerical value of a digital recording instrument recorded at a specific instant 3.1.5 full-scale deflection minimum input value, which produces the nominal maximum output of the digital recording instrument in the specified range 3.1.6 offset output of a digital recording instrument for zero input 3.1.7 raw data original record of sampled and quantized information obtained when a digital recording instrument converts an analogue signal into a digital form, with the correction of the output for offset and multiplying the record by a constant factor being permitted 3.1.8 test duration range of a time interval in which the measurement is done 3.1.9 reading rate rate with which the instrument displays or stores the readings of the measured AC or DC voltage or current
