is the shunt impedance (0.6 Ω for 1 A shunt, 9.375 mΩ for 30 A shunt). It is assumed that the waveform measured is a sine wave.
Measurement conditions during calibration: Instrument default settings unless otherwise stated, Sine waves applied to V and I inputs, 30 minute warm-up, Temperature 23 °C ±5 °C.
