Digital Channel Waveform and Label Colors 
 
When the digital channel is turned on, the corresponding channel waveform and 
label are displayed on the screen. The channel waveform and label colors are related 
to the current active digital channel.  
 
Digital Channel Waveform Color 
  If the current active digital channel is a digital channel, the waveform of the 
channel is in red; the logic high levels in the waveforms of the other digital 
channels turned on are in blue and the logic low levels in green with the edges in 
white.  
  If the current active digital channel is a user-defined channel group, the 
waveform of the first channel (according to the channel number sequence) in 
the channel group is in red; the logic high levels in the waveforms of the other 
digital channels (the other channels in this user-defined channel group) turned 
on are in blue and the logic low levels in green with the edges in white. 
 
Digital Channel Label Color 
  The label of the active digital channel is displayed in red.  
  When Group1 is turned on, the labels of all the digital channels in it are 
displayed in purple.  
  When Group2 is turned on, the labels of all the digital channels in it are 
displayed in pink. 
  When Group3 is turned on, the labels of all the digital channels in it are 
displayed in blue. 
  When Group4 is turned on, the labels of all the digital channels in it are 
displayed in light blue. 
  The labels of the other digital channels turned on are displayed in green.  
 
Note: The channel label color rules above are listed according to their priorities 
(from high to low).
