CHAPTER 1 ACCIDENCE

Digital Storage Oscilloscope is mini-type and portable bench type instruments, 
which could be used for measuring as the GND voltage. 
This Chapter shows you how to operate following tasks:

The oscilloscopes provides an easy-to-use front panel to convenience users to 
operate them, the panel contains knobs and buttons. There is a list of five ashen 
buttons as menu operational buttons on the right of display screen. You can set 
different options of the current menu in virtue of them. Other buttons are function 
buttons; you can enter different function menus or obtain given function 
application in virtue of them. 

It is important for you to understand the DSO's front panel before operating it. 
The following contents are the brief introduction for the front panel function, 
which is useful to be familiar with the operation of the Digital Storage 
Oscilloscope in short time.
