 Check whether the vertical scale factor is set correctly
 Check whether trigger source, trigger conditions are set correctly
 Check whether the instruments are in waiting state for trigger
 Press to resample signal
3) If the measured voltage amplitude is 10 times greater or 10 times smaller than the
practical value:
 Check whether the settled attenuation factor of the channel is in accordance
with the attenuation factor of the used probe.
4）If the waveform is moving continuously on the screen and cannot be triggered:
 Check the trigger source to ensure that it is consistent with the input channel.
 Check the trigger type: edge trigger for general signal; video trigger mode for
video signal. Only use the correct trigger mode, could display stable
waveform.
