To Adjust the Horizontal Time Base 
Horizontal time base, also called the horizontal scale, refers to the time of each grid 
in the horizontal direction of the screen. It is usually expressed in s/div. The 
adjustable range of the horizontal time base is related to the model type. 
While you change the horizontal time base, the displayed waveforms of all channels 
are expanded or compressed horizontally relative to the current selected horizontal 
reference baseline (refer to "Horizontal Expansion"). The horizontal time base at 
the upper-left corner of the screen will be changed accordingly, as shown in the 
figure below. 
You can adjust the horizontal time base with the following three methods: 
  Rotate Horizontal    SCALE to adjust the horizontal time base within the 
available range (clockwise to reduce the horizontal time base and 
counterclockwise to increase).   
  Enable the touch screen function and adjust the horizontal time base with the 
pinch & stretch gesture on the touch screen. For details, refer to the "Pinch & 
Stretch" section. 
  Enable the touch screen function, and tap the horizontal time base label 
  at the top of the screen. The following window is displayed. Tap the 
  icon at the right side of the Timebase input field to increase or 
decrease the horizontal time base. You can also tap the Timebase input field to 
input a specific value with the displayed numeric keypad. 
In the Horizontal control area (Horizontal), rotate the Horizontal    SCALE knob 
to switch the adjustment mode between "Coarse" and "Fine" (by default, it is Coarse). 
You can also press Acquire  More  Fine to enable or disable the fine 
adjustment of the horizontal time base. 
  Coarse  adjustment:  Rotate  the  Horizontal    SCALE  knob  will  adjust  the 
horizontal time base of the waveforms of all channels at 1-2-5 step within the 
adjustable range. Rotate it clockwise to reduce the horizontal time base, and 
counterclockwise to increase the horizontal time base. 
  Fine  adjustment:  Rotate  the  Horizontal    SCALE knob  will  adjust  the 
horizontal time base of the waveforms of all channels with a minor step value 
within the adjustable range. Rotate it clockwise to reduce the horizontal time
