Average calculation
Signed average: Signs of values are included in average calculation.
"(AVG)" following a parameter indicates the average result.
*1 PF/DPF average calculation
Addition processing : If the power factor value is negative, it is multiplied by (-1). If the power factor value is positive, it is multiplied by
(-1), and the value 2 is added. The resulting value is integrated.
Averaging processing : The result of addition processing described above is divided by the number of added data points. If the result is
less than 1, it is multiplied by (-1). If it is greater than or equal to 1, it is multiplied by (-1), and the value 2 is added.
*2 Phase average calculation
Uphase average calculation
Uckr and Ucki represent the signed averages for each channel.
Iphase average calculation
I
Ickr and Icki represent the signed averages for each channel.
Pphase average calculation
(Channel averaging processing) : Qharmk and Pharmk represent the signed averages for each channel.
(Sum averaging processing) : Qsumk and Psumk represent the signed averages for each channel.

formula described in Note 1 below.
This calculation is used for both PF and DPF.
Uunb RMS - Same applies to Uunb0.
Iunb RMS - Same applies to Iunb0.
Uharm RMS - For content percentage and order 0, signed average.
Same applies to Uiharm.
Iharm RMS - For content percentage and order 0, signed average.
Same applies to Iiharm.
Pharm Signed average Average results for all channels are to-
taled.
The content percentage is calculated from the sum value
calculated from the level.
