Measurement error = (Energy Measured By Device - True Energy)/True Energy * 100%. Accuracy is
measured with signal (±660 mV) on Channel 1. F
See Section 2.0 “Typical Performance Curves” for higher frequencies and increased dynamic range.
Does not include internal V
measured output frequency and expected transfer function.

50 Hz, CH2 = 100 mVRMS @ 50 Hz, AV
Error applies down to 60° lead (PF = 0.5 capacitive) and 60° lag (PF = 0.5 inductive).
Refer to Section 4.0 “Device Overview” for complete description.
Specified by characterization, not production tested.
1 MCLK period at 3.58 MHz is equivalent to less than <0.005 degrees at 50 or 60 Hz.
Gain error match is measured from CH0 G = 1 to any other gain setting.
