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 if 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 if the probe is correctly connected to the
oscilloscope and the item under tested.
(2) Check if 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
only occurs when probe is used):
Check whether the attenuation coefficient of the channel
