The phase and size (rms value) relationship between the fundamental signals U(1) and
I(1) of each element in wiring unit Σ can be displayed using vectors. The positive vertical
axis is set to zero (angle zero), and the vector of each input signal is displayed.
Note
If the analysis window width (number of cycles of the fundamental signal) that is determined by
the fundamental frequency is shorter than the data update interval, vectors are not displayed. If
this happens, decrease the data update rate. The details are the same as with harmonic data.
See the "Note" part of section 6.2.
Turning the Display of Numeric Data On or Off
You can select whether or not to display numeric data (by selecting ON or OFF). The
signal sizes and the phase differences between the signals can be displayed along with
the vector display. For information about phase difference display formats, see section 5.5.
Setting the Vector Zoom Factor
The size of the vectors can be changed.
• The zoom factor can be set in the range of 0.100 to 100.000.
• You can specify separate zoom factors for the fundamental signals U(1) and I(1).
Note
If all the wiring systems are single-phase, two-wire (1P2W) or if you are using the single input
element model, the wiring unit
display.

does not exist. Therefore, nothing is displayed in the vector
