Please note
The influence of the HF-Rejection filter is compensated for the amplitudes of the harmonics.
The values for U, I and P are not recalculated from the harmonics, but are calculated from the
sampling values to get for example interharmonics and components with higher frequencies
which are not captured by the harmonics. So it is not possible to compensate the influence of
the filters for this values! For the same reason this values can also be much bigger than the
values which can be derived from the harmonics (depending on the signal).

Mode
Amplitude error
The error of the harmonic with the biggest amount H
max
(usually the fundamental) and of the
DC part (H
00
) is calculated as if each part is measured alone (refer error specifications of the
normal measuring mode).
The errors of the harmonics (H
01
, H
02
, ...) except H
max
is calculated as follows:
