Waveform capture 143

The cursors can be moved in one of two ways: either by clicking and dragging them left and
right across the duration period of the signal, or by using the Cursor 1 and Cursor 2 scroll bars at
the top of the window. The red line is the trigger position, which cannot be moved across the
captured waveforms.
The numeric amount listed in the corresponding colored box to the left of the signal indicates
the magnitude of the signal at the point where the cursor is located. There are also Cursor 1,
Cursor 2, and Delta boxes at the top of the window, which indicate the exact point in time for
that cursor position.
Zooming - To zoom in on a selected section of waveform(s), right-click or click the Zoom In
button and drag the outline box over the desired area. Multiple zooms are possible. To zoom out,
right-click or click Zoom Out.
Save to USB - Will save the waveform as a comtrade file to a USB memory stick.
To superimpose waveforms, select the waveform to be moved by left-clicking on the X-axis and
dragging it to the desired position.
Displayed on the left side of the window are parameter fields, as shown in Figure 9-8:
Figure 9-8 Parameter fields
•
The blue field displays the parameter value at the blue Cursor 1 position.
•
The green field displays the parameter value at the green Cursor 2 position.
•
The yellow field indicates the relative parameter difference between the two cursor
amplitude values.
•
The vertical red line indicates the trigger position (%) of the data capture.
•
Located just above the Parameter fields on the right are three buttons. These three buttons
corresponds to the Cursor 1, Cursor 2 and the delta values being displayed. When turned off,
the corresponding values are not displayed in the numerical chart. All three switches are on
by default.
