Troubleshooting
The commonly encountered failures and their solutions are listed below. When you
encounter those failures, please solve them following the corresponding steps. If the
problem remains still, please contact
RIGOL and provide your device information
(acquisition method: Utility  System  System Info).
1. The screen is still dark (no display) after power on:
(1) Check whether the power switch is turned on.
(2) Check whether the power is correctly connected.
(3) Check whether the fuse is burned out. If the fuse needs to be changed,
please use the specified fuse.
(4) Restart the instrument after finishing the above inspections.
(5) 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 item under tested.
(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 problem, 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 only occurs when probe is used):
Check whether the attenuation 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: press MENU of the TRIGGER Control Area
of the front panel, then press Source to confirm whether the setting
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 of the signal.
(4) Change the trigger holdoff setting.
