(4) Change the trigger holdoff setting.
5. No display after pressing RUN/STOP:
Check if the MODE at the front panel TRIGGER control area is on "Normal" or
"Single" and if the trigger level exceeds the waveform range. If yes, set the
trigger level to the middle or set the MODE to "Auto".
Note: using AUTO could automatically finish the above setting.
6. The display of waveform is ladder-like:
(1) The horizontal time base might be too low. Increase the horizontal time
base to increase the horizontal resolution and improve the display.
(2) If Type is "Vectors", the lines between the sample points may cause
ladder-like display. Set Type to "Dots" to solve the problem.
7. Fail to connect PC through USB:
(1) Check if the USB data cable is correctly connected to the oscilloscope and
PC.
(2) Check if the USB data is in good condition and if needed, restart the
oscilloscope.
8. The USB disk can not be recognized:
(1) Check if the USB disk can work normally.
(2) Make sure that the USB disk being used is flash type. This oscilloscope does
not support hardware type USB disk.

that the capacity of the USB disk being used with this oscilloscope is no
larger than 8 GBytes.
