•  When Event Fix Mode Is Set to Mode1
  Events detected at positions other than the master event positions are also displayed in the 
event list.
   
Events other than fixed events 
are also detected.
An earlier event is detected, so the 
number of this fixed event is updated 
(changes from 3 to 4).
•  When Event Fix Mode Is Set to Mode2
  Only the events that are detected at the master event positions are displayed in the event list.
   
Not detected even when an event exists.

• Legacy
  The waveform display range is zoomed. For example, if you expand the waveform display range 
to the entire waveform, the displayed waveform will appear smaller. If you reduce the waveform 
display range to a portion of the waveform, the displayed waveform will appear larger.
