control area. Practices below will gradually guide you to get familiar with the controlling of 
the vertical system.

(1)  Vertical POSITION: vertical position knob, user can change the current vertical position 
of  channel  waveform,  the  vertical  position  value    will  display  on  the 
baseline cursor area. Press this knob to get the dispayed channel position back to the 
vertical center. 
If the coupling mode of channel is DC, user can fast measure the DC component 
of signal by observing the difference between waveform and signal ground. 
If the coupling mode of channel is AC, the DC component in the signal will be 
filtered, which helps to display AC component of signal with higher sensitivity. 
(2)  Vertical SCALE: Change vertical setting and observe the change of status information. 
User can confirm any change of vertical scale level by the information displayed on the 
status  bar.  Rotate  the  vertical  scale  knob  to  change  the  vertical  scale  level  of 
“VOLTS/DIV”, and then the scale level of channel on the stauts bar will be changed 
accordingly. Press CH1, CH2, MATH to display operation menu, symbols, waveform 
and scale level status of corresponding channels. Double click CH1, CH2, MATH to 
turn off the channel. 
 
1.6 Introduction to the Horizontal System 
As shown in the figure below, there is one key and two knobs within the horizontal control 
area. Practices below will gradually guide you get familiar with the setting of horizontal time 
base.
