29、IEC 61083 is applicable to digital recorders, including digital oscilloscopes, analogue oscilloscopes and peak voltmeters used for measurements during tests with high impulse voltages and high impulse currents. It specifies the measuring characteristics and calibrations required to meet the measurin
30、g uncertainties and procedures specified in IEC 60060-2. This part defines the terms specifically related to digital recorders, analogue oscilloscopes and peak voltmeters, specifies the necessary requirements for such instruments to ensure their compliance with the requirements for high-voltage and
31、for high-current impulse tests, and establishes the tests and procedures necessary to demonstrate their compliance. Only digital recorders that permit access to raw data from permanent or temporary storage are covered by this standard. The raw data, with relevant scaling information, may be printed
32、graphically, or stored in digital format. 1.2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 61083.
