Axis display
You can select whether to use a linear display (LINEAR) or logarithmic display (LOG) for the vector axis.
If you select the logarithmic display method, the vector is easy to see even at low levels.
RMS/phase angle/content percentage display
Selects which value to display (RMS value display, phase angle display, or content percentage display). If
[Phase] is selected, you can also set the phase angle value display method.
Phase angle value display method
You can select the type of phase angle display. (This setting can be configured only when [Phase] is
selected.)
Setting this parameter to
[lag360]
allows the display to be rotated clockwise 0° to 360°.
If
[lag360]
is selected, you can also set the phase angle reference source.
Phase angle reference source
You can select the reference source (0°) to display the phase angle
value.
