Split after pressing this button the display will be split in four separated graphs, refer the
following picture:
Figure 29: The plot display; split on
Hint: the settings of the cursor are the same for all four to get accurate readings at the selected
moment for all channels.
Fit By this the actual selected graph (A to D) is rescaled to fit into the screen.
5.4.6.3 Vec. A/B
The settings in group A and B are identical, so they are just described once.
On this tabs you see the vectors of voltage and current (Fresnel diagramm). In the lower left
corner you see the amplitude and the phase angle of the selected signal. In the upper right
corner you see the rotating direction of the vectors and the phase counting of the voltages.
‘1,2,3’ means that the zero crossings are in the order 1

phase. ‘3,2,1’ means that you
have the opposite order. By pressing the rotary knob you can do the following settings:
Signl Here you can choose the signal to be displayed. The possible values are voltage or
current.
Ref. Here you can choose the reference for the angles:
U U1 is set to 0°
I I1 is set to 0°
None The sync. signal is used as 0° reference.
All angles which are displayed in this menu are relative to this reference angle.
Zoom You can zoom the selected signal to get longer vectors.
