To Understand the Vertical System 
 
As shown in Figure 1-8, there are several buttons and knobs in the VERTICAL 
control area, which are used for setting Channels, MATH and REF functions as well as 
adjusting vertical position and Volts/div of waveforms. In addition, different colors 
are designed for different channels, corresponding to different waveforms, so as to 
observe clearly.

1.  Press  CH1,  CH2,  CH3,  CH4,  MATH,  REF,  the operating  menus,  symbols, 
waveforms and status information of corresponding channel and settings will be 
displayed on the screen. The current selected channel will be shut down when 
you press the key associated with the channel one more time. 
 
2.  Set vertical position of waveform display by 
 knob. 
Turning the 
 knob, a voltage value is displayed for a short time 
indicating its value with respect to the ground reference located at the center of 
the screen. Also notice that the ground symbol on the left side of the display 
moves in conjunction with the
 knob.
