  Figure 1-4     

(4) If necessary, adjust the probe and repeat the operation if necessary. 

 

Chapter 2 Describes of the function and operation 

 

In order to use ADO Series oscilloscope effectively, you need to understand the main 

functional framework of the oscilloscope. 

 

 

This chapter is divided into three modules to introduce oscilloscope according to the 

functional framework: automotive oscilloscope, general oscilloscope, multimeter.
