To Set the Channel Label 
 
By default, the oscilloscope uses the number of the channel (such as 
, displayed 
at the left of the screen) to mark the corresponding analog channel. For easier use, 
you can define a label for each analog channel. 
 
The label modification interface is as shown in the figure below. 
 
 
 
 
Name Input Area: display the label characters currently input; 
Keyboard: used to input the specified character; 
Upper/Lower Case Switch: used to switch between English uppercase and 
lowercase inputs. “
A
a” denotes lowercase and “
a
A” denotes uppercase. 
 
Note: The user-defined label can include uppercase English letters (from A to Z), 
lowercase English letters (from a to z), numbers (from 0 to 9), underline and space; 
the length of the label cannot exceed 4 characters.  
 
For example, change the label of CH1 to “Chn1”. 
 
1.  Press CH1 Label to open the lable submenu and the label modification 
interface (as shown in the figure above).  
If there are characters in the “Name Input Area”, please press Delete 
continuously to delete all the characters.
