Chapter 16 Troubleshooting
The commonly encountered failures and their solutions are listed below. When you
encounter those problems, please solve them following the corresponding steps. If
the problem remains still, please contact RIGOL and provide your device
information (Utility  System  System Info).
1. The screen is still dark (no display) after pressing the power key:
(1) Check whether the power is correctly connected.
(2) Check whether the fuse is burned out. If the fuse needs to be changed,
please use the specified fuse.
(3) Restart the instrument after finishing the above inspections.
(4) If it still does not work correctly, please contact RIGOL.
2. The signal is sampled but no waveform of the signal is displayed:
(1) Check whether the probe is correctly connected to the oscilloscope and the
item under test.
(2) Check whether there are signals generated from the item under test (you
can connect the probe compensation signal to the problematic channel to
determine which has problems, the channel or the item under test).
(3) Resample the signal.
3. The voltage amplitude measured is greater or lower than the actual
value (note that this failure usually occurs when probe is used):
Check whether the probe ratio of the channel complies with the attenuation ratio
of the probe.
4. There is waveform display but not stable:
(1) Check the trigger signal source: check whether MENU  Source in the
trigger control area (TRIGGER) complies with the signal channel actually
used.
(2) Check the trigger type: general signals should use “Edge” trigger and video
signal should use “Video” trigger. Only when the proper trigger type is used,
can the waveform be displayed stably.
(3) Check the trigger level: adjust the trigger level to the middle position of the
