To adjust the vertical offset
• Click and hold the left mouse button on the waveform you want to 
move, then drag the mouse up or down to move the waveform to the 
desired offset.  Release the mouse button when finished.
or
• Click and hold the left mouse button on the ground reference indicator 
for the waveform you want to move, then drag the mouse to move the 
waveform to the desired offset.  Release the mouse button when 
finished.
or
• Click the channel button in the vertical toolbar, then set the vertical 
offset using the spin box control in the Channel Setup dialog box.
If you leave the mouse pointer on the waveform (without clicking the mouse), 
the pointer changes into crossed arrows as a visual indicator that you can drag 
the waveform when you click and hold th e mouse button.  If you move the mouse 
up or down, the interface constrains the movement vertically and adjusts 
vertical offset only.  If you initially move the mouse left or right, the interface 
constrains the movement horizontally and changes the horizontal position 
setting only.
You can also adjust the vertical offset through the Channel Setup dialog box.
