10.3 AUTO strategy 

As mentioned before, press AUTO button to activate the function of Waveform Auto Setting. 

To  get  a  best  diplay  waveform,  DSO  automatically  adjust  vertical  scale,  horizontal  time 

base  and  trigger  mode  based  on  input  signals.  This  DSO  allow  users  to  set  relevant 

parameters of auto setting function.
