Notes:

All stated accuracies are based upon a minimum of a 30-minute warm-up period.

Zext is the external shunt impedance used and must be less than or equal to 10 Ohms.

If no frequency is measured, then the signal is considered DC for the purpose of accuracy.

F is the frequency measured in kHz. In the case of harmonics, F is the harmonic frequency.

Specifications are valid from 1 to 100% of range in low bandwidth and after a manual zero has been performed. Values below 1% are typical.

In high bandwidth, specifications are valid when the signal is greater than 10% of the range.

Harmonic specifications are always valid when the harmonic is greater than 2% of the range.

Measurement conditions during calibration: Instrument default settings unless otherwise stated, sine waves applied to V and I inputs, 30 min warm up, ambient temperature 23 °C ±5 °C.
