5. No display after pressing RUN/STOP:
Check whether the MODE at the front panel trigger control area (TRIGGER) is
on “Normal” or “Single” and whether 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 waveform displayed 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 Display Type is “Vectors”, the lines between the sample points may
cause ladder-like display. Set Type to “Dots” to solve the problem.
