D.1 Measuring instrument
The measuring instrument of Figure D.1 is from Figure 4 of IEC 60990.
The measuring instrument is calibrated by comparing the frequency factor of U2 with the solid line in Figure F.2 of IEC 60990 at various frequencies. A calibration curve is constructed showing the deviation of U2 from the ideal curve as a function of frequency.
