a
Average or maximum of 3 voltage channels in 3Φ4W3E and 3Φ3W2E input mode, 1 channel in 1Φ2W1E mode,
and 2 channels in other modes. In 3Φ3W2E mode, the voltage VAC is derived internally by point-by-point calculation
after A/D conversion. The voltage VB, synthesized internally in 3Φ4W2-1/2E mode, does not correspond to an actual
physical quantity and is not included in the analysis, although measurements can be made on the synthesized signal.
b
Average or maximum of 3 current channels in 3Φ modes, 1 channel in 1Φ2W3E mode, and 2 channels in other
modes. In 3Φ3W2E mode, the current IB is derived internally by point-by-point calculation after A/D conversion.
c
Total of 3 elements in 3Φ4W3E and 3Φ4W2-1/2E modes, 1 element in 1Φ2W1E mode, and 2 elements in other
modes.
