6.10.7.2 Accuracy of Amplitude Measurement
The measurement values are given as effective values (rms).
The permitted input frequency range for the fundamental wave depends on
the specified sampling rate:

Sampling rate and input
frequency range
Valid for fundamental and harmonic waves in specified frequency range; accuracy
refers to full scale.
