Vector screen
Press to display the Vector screen. The Vector screen displays one of volts,
amps, or volts and amps harmonic information in the form of a vector diagram.
Figure 11: Vector screen
Vectors will be displayed on a per-group basis. The left and right arrow hard keys
change the currently displayed group. The active group is displayed in the top left
corner in the appropriate group color.
The left and the right soft keys change the harmonic number currently being
displayed. The harmonics available for display will be the same as the harmonics
in the results screen. There are two differences. The firstisthatiftheresults
screen is configured to display magnitudes as a percentage of the fundamental, the
absolute magnitude will still be used. This will allow a true comparison between
the magnitudes of the selected harmonic for each channel in the group. The
second is that if the user has not enabled harmonics to display, then the harmonic
setup will still be used. This provides a quick way to view harmonic information
without displaying harmonics.
The V/A top soft key toggles the display between displaying volts vectors only,
amps vectors only, and both volts and amps vectors.
Each vector displayed is sho wn in a different color. There can be up to six vectors
displayed on the graph at one time. This would be a for a 3p4w configuration
showing volts and amps.
In addition to displaying a vector line, the magnitude and phase angle of the vector
are displayed to the right of the vector diagram. Both the voltage and current
information is shown even if the vector is not.
