RIGOL  Chapter 2 To Set the Vertical System 
2-4  MSO7000/DS7000 User Guide 
⚫  Coarse adjustment (take counterclockwise as an example): Rotate Vertical   
SCALE to set the vertical scale at 1-2-5 step, i.e. 500 μV/div, 1 mV/div, 2 mV/div, 
5 mV/div, 10 mV/div…10 V/div. 
 
 
Vertical Expansion 
 
When changing the vertical scale of the analog channel by rotating the Vertical   
SCALE knob, you can select to expand or compress the waveform around the 
"Center" or "GND" (Ground). By default, "GND" is selected under Expand. 
 
Press 1 → More, then press Expand continuously to select "Center" or "GND". 
⚫  Center: when the vertical scale is changed, the waveform will be expanded or 
compressed around the screen center. 
⚫  GND: when the vertical scale is changed, the waveform will be expanded or 
compressed around the signal ground level position. 
 
 
To Adjust the Vertical Offset 
 
Vertical offset indicates the offset of the signal ground level position of the waveform 
from the screen center in the vertical direction. Its unit is consistent with the 
currently selected amplitude unit (refer to "Amplitude Unit"). When adjusting the 
vertical offset, the waveforms of the corresponding channel moves up and down. 
The vertical offset information (as shown in the following figure) in the channel 
status label at the bottom of the screen will change accordingly. 
   
 
The adjustable range of the vertical offset is related to the current input impedance, 
probe ratio, and vertical scale.   
 
When CH1 is turned on, you can adjust the vertical offset with the following four 
methods: 
⚫  Rotate Vertical    OFFSET that corresponds to CH1 to adjust the vertical 
offset within the adjustable range. Rotate this knob clockwise to increase the 
vertical offset, and rotate it counterclockwise to reduce the vertical offset. 
Pressing down the knob can quickly reset the vertical offset (set the vertical 
offset to 0). 
⚫  Menu setting: Press 1 → More → Offset, and then the numeric keypad is 
displayed. Input the offset value with the numeric keypad.   
⚫  Enable the touch screen, and then adjust the vertical offset with the drag 
gesture. For details, refer to the "Drag" section. 
⚫  Enable the touch screen function, and tap the channel status label at the bottom
