Display Control
In the "display" setting menu, you can set the parameters such as the waveform
display type, persistence time, intensity, grid type, grid brightness, and etc.
20.1 To Select the Display Type
Press to enter the display control setting menu. Press Type continuously to set
the waveform display mode to "Vector" or "Dots".
• Vector: the sample points are connected by lines and displayed. In most cases,
this mode can provide the most vivid waveform for you to view the steep edge
of the waveform (such as square waveform).
• Dots: the sample points are displayed directly. You can directly view each sample
point and use the cursor to measure the X Value and Y values of the sample
point.

20.2 To Set the Persistence Time
Press Persis.Time, and rotate the multifunction knob to set the persistence time
for the oscilloscope and then press down the knob to select it. You can also press
Persis.Time continuously or enable the touch screen to select it. The available values
are Min, specific values (i.g. 100 ms, 200 ms, 500 ms, 1 s, 2 s, 5 s, 10 s), and Infinite.
In the following part, a frequency sweep signal of the sine waveform is used to show
the waveform effects in different persistence times.
