How to Implement Self-calibration  
The self-calibration application can make the oscilloscope reach the optimum condition 
rapidly to obtain the most accurate measurement value. You can carry out this application 
program at any time. This program must be executed whenever  the change  of ambient 
temperature is 5℃ or over. 
Before  performing  a  self-calibration,  disconnect  all probes or wires from  the input 
connector. Push the Utility button, select Function in the bottom menu, select Adjust. in 
the left menu, select Self Cal in the bottom menu; run the program after everything is 
ready. 
Introduction to the Vertical System  
As shown in Figure 3-11, there are a few of buttons and knobs in Vertical Controls. The 
following practices will gradually direct you to be familiar with the using of the vertical 
setting.  
Figure 3-11 Vertical Control Zone   
1.  Use the Vertical Position  knob to show the signal in the center of the waveform 
window. The Vertical Position knob functions the regulating of the vertical display 
position of the signal. Thus, when the Vertical Position knob is rotated, the pointer 
of the earth datum point of the channel is directed to move up and down following 
the waveform. 
Measuring Skill  
If the channel is under the DC coupling mode, you can rapidly measure the DC 
component of the signal through the observation of the difference between the wave 
form and the signal ground. 
If the channel is under the AC mode, the DC component would be filtered out. This 
mode helps you display the AC component of the signal with a higher sensitivity.
