format plots the voltage on CH1 against the voltage on CH2, where CH1 is the horizontal axis and CH2 is 
the vertical axis. The oscilloscope uses the untriggered Normal acquisition mode and displays data as 
dots.   
The  oscilloscope  can  acquire  waveform  in  YT  mode  at  any  sampling  rate.  You  may  view  the  same 
waveform in XY mode. To perform this operation, stop the acquisition and change the display mode to 
XY. 
2.12.3. Roll Mode 
In Roll  mode, the waveform display rolls  from right to left. No trigger or horizontal offset control of 
waveform is available during Roll Mode, and it’s only available when set to 100ms/div or slower. 
2.13. Display 
The waveform display is affected by settings of the oscilloscope. A waveform can be measured once it is 
captured. The different styles to display a waveform on the screen give significant information about it. 
Push the [Display] button and the following menu appears. 
Vectors fill  up  the  space  between adjacent  sample  points  in  the display; 
Dots only displays the sample points. 
Adjustable, Turn the multi-functional knob to adjust.

2.14. Utility System 
Push the UTILITY button to display the Utility Menu as follows. 
Insert a USB disk with upgrade program. Press the Update Program button and the Software 
Upgrade window pops up. Refer to tips to upgrade or cancel.
