IEC 61083-1 pdf – Instruments and software used for measurements in high-voltage and high-current tests – Part 1: Requirements for instruments for impulse tests
This part of lEC 61083 is applicable to digital recorders，including digital oscilloscopes,usedfor measurements during tests with high impulse voltages and high impulse currents. It specifiesthe measuring characteristics and calibrations required to meet the measuring uncertaintiesand procedures specified in lEC 60060-2 and lEC 62475.
This document
.defines the terms specifically related to digital recorders;
specifies the necessary requirements for such instruments to ensure their compliance withthe requirements for high-voltage and high-current impulse tests;
establishes the tests and procedures necessary to demonstrate their compliance;
covers digital recorders that permit access to raw data from permanent or temporary storage;covers peak meters used for measuring the extreme value of lightning impulses, the peakvalue of switching or current impulses.
lt has the status of a horizontal standard in accordance with IEC Guide 108.
This horizontal standard is primarily intended for use by technical committees in the preparationof standards in accordance with the principles laid down in lEC Guide 108.One of theresponsibilities of a technical committee is,wherever applicable,to make use of horizontalstandards in the preparation of its publications. The contents of this horizontal standard will notapply unless specifically referred to or included in the relevant publications.

3.1.1
digital recorderdigitiser
recording instrument in which the recording is made in digital form on a magnetic or opticalmedium, or on a solid-state memory medium
Note 1 to entry: The waveform of the digital record is usually displayed on a screen, plotted or printed. This processmay change the appearance of the waveform due to the processing involved.

3.1.2
approved digital recorder
digital recorder that is shown to comply with the requirements set out in this document
3.1.3
assigned measurement range
range of input voltage for which the instrument can be used within the uncertainty limits givenin this document
3.1.4
output of a digital recorder
numerical value recorded by a digital recorder at a specific instant
3.1.5
full-scale deflection
minimum input voltage, which produces the nominal maximum output of the instrument in thespecified range
3.1.6
offset
output of an instrument for zero input
3.1.7
raw data
original record of sampled and quantized information obtained when a digital recorder convertsan analogue signal into a digital form, with the correction of the output for offset and multiplyingthe record by a constant factor being permitted
3.1.8
processed data
data obtained by any processing (other than correction for offset and/or multiplying by aconstant scale factor) of the raw data
