1. 

Press F1 to open the cursor measurement;

 

2. 

Press F2 to select a type of cursor measurement.

 

3. 

Press F3 to select the channel that needs to be measured.

 

4. 

Press F4 to enter the second page, press F1 or F2 to select Cursor1 or Cursor2, press 

up, down, left and right to move Cursor1 or Cursor1;

 

5. 

The result of cursor measurement will be displayed on the cursor menu.

 

Automatic Measurement

 

The oscilloscope provides 2 kinds of automatic measurements, including frequency 

and amplitude.

 

Press 

Menu

 button to enter, select 

Measure

 to enter automatic measurement. Press 

F1 

to open, the measurement results will be displayed in the top left corner of the 

screen.

 

Attention

:

 

In the measurement result, the yellow font is the result of CH1, and the green font is 

the result of CH2.
