15 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 (acquisition method: UTIL ïƒ System ïƒ System Info).
1. The screen is still dark (no display) after power on:
(1) Check whether the power is correctly connected or if the battery is correctly
installed.
(2) Check whether the power switch is really on.
(3) Check whether the fuse is burned out. If the fuse needs to be changed,
please return the instrument to the factory and the RIGOL authorized
personnel will change the fuse for you.
(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 oscilloscope and the
item to be 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 problems, the channel or the item under test).
(3) Resample the signal.
3. The tested voltage amplitude is greater or lower than the actual value
(note that this problem usually occurs when probe is used):
Check whether the attenuation coefficient 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 in the trigger control area
(TRIGGER) on the front panel; check whether the setting of Source
complies with the signal channel actually used.
(2) Check the trigger type: general signals should use "Edge" trigger and video
