Using the Marker Lines
Waveform and RMS panes have two blue dashed marker lines. The left marker
indicates the position from where data will be taken to calculate the harmonics
spectrum and phasor diagrams, and also the starting position for calculating the
RMS, average and peak values. The right marker indicates the end position for
calculating the RMS, average and peak values. The minimum distance between the
two markers is exactly one cycle.
To change the marker position, click with the right mouse button on the waveform
window, select 'Set Marker', and then click with left mouse button on the point
where you want to put the marker. You can also drag both markers with the
mouse, or use the right and left arrow keys on your keyboard to change the marker
position. Before using the keyboard, click on the waveform pane with the mouse,
to allow the keyboard to get your input.
Using a Zoom
You can use a horizontal and a vertical zoom to change size of your waveforms.
Use the buttons
on you local toolbar representing green
arrowheads to zoom in or out of the waveform graph. Every click on these buttons
gives you a 100-percent horizontal or 50-percent vertical zoom. Two buttons
representing a magnifying glass give you a proportional zoom in both
directions.
When in the overlapped waveform view, you can zoom in on a selected waveform
region. Click with the right mouse button on the waveform window, click 'Zoom',
point onto one of the corners of the region you want to zoom in, press and hold
the left mouse button, then point to another corner of the selected region and
release the mouse button.
Viewing Waveforms
Waveforms can be displayed in two views: overlapped and non-overlapped. To
select the first view, click on the button
representing a single waveform on the
