to  correctly  trigger  the  signal  and obtain  a  stable  waveform.  Press  Level  Select 
(when "<>" is selected as the trigger condition, Level Select is a sub-menu under 
More), then rotate the multifunction knob    to select the desired level  type for 
adjustment, and then press down the knob to select the type. You can also press 
Level Select continuously to select the level type or enable the touch screen to tap 
the desired level type and select it.   
  Level A: only adjusts the upper limit of the trigger level, and the lower limit of 
the trigger level remains unchanged. 
  Level B: only adjusts the lower limit of the trigger level, and the upper limit of 
the trigger level remains unchanged. 
  Level AB: adjusts the upper and lower limits of the trigger level at the same time, 
and the trigger level deviation (the difference between the upper limit and lower 
limit of the trigger level) remains unchanged. 
Note: In Slope trigger, pressing Trigger    LEVEL can quickly switch the current 
level adjustment type.   
Rotate the Trigger    LEVEL knob to adjust the corresponding trigger level. During 
the adjustment of trigger level, two trigger level lines appear on the screen, and they 
move up and down with the change of the trigger level. At the same time, the 
real-time trigger level information is displayed at the lower-left corner of the screen 
(as shown in the figure below, H indicates the upper limit of the trigger level, L 
indicates the lower limit of the trigger level, and  △  indicates the trigger level 
deviation). When you stopping modifying the trigger level, the trigger level line and 
the trigger level information at the lower-left corner of the screen disappear in about 
2 s. The current trigger level deviation is displayed at the upper-right corner of the 
screen.
