6. Display speed is slow after average sampling
If average sampling is carried out for more
than 32 times, the display speed will drop. This is
You can reduce the intervals of average
7. Trapezoidal waveform display :
This is normal. The reason is possibly
horizontal time base range is too low. You can
improve horizontal resolution and enhance the
display quality by increasing the horizontal time
If the display type is vector, the connection
between sampling dots may cause a trapezoidal
waveform. Set the display type to dot to solve
Chapter 5 Using the USB update
The USB upgrade program makes upgrade easier and
more flexible. To use this function follow the steps
