Z_ext is the shunt impedance and must be less than or equal to 10 ohms.

Specifications are valid only when applicable voltage and current inputs are >10% of range. The exception is harmonics where the specification is valid when the magnitude of the harmonic is >2% of range.

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.
