 Check the noisy signal source. Set the trigger coupling mode to
high-frequency inhibition or low-frequency rejection to filter out high
frequency or low frequency interference
 Check whether the trigger hold-off time is appropriate
5）If there is no any display after pressing :
 Check whether the triggering mode is ‘normal’, and whether the trigger level
is beyond the scope of the waveform. Center the trigger level and set the
trigger mode as auto
 check whether the time is too long for level delay
 Test whether the trigger hold-off time is too long
6）If the display becomes slow down after setting average times of sampling:
 If the average times are above 32, it is normal for the general speed.
 You can reduce the average times
