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 signal connecting wire.

(2) Check if the signal connecting wire is correctly connected to the BNC

(namely channel connector).

(3) Check if the probe is correctly connected to the item under tested.

(4) 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).

(5) 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 complies with the attenuation ratio of the probe.

4. There is waveform display but not stable:

(1) Check the trigger signal source: check whether the Source item at the trigger panel 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) Change the trigger holdoff setting.

5. No display after pressing RUN/STOP:

Check if the MODE at the trigger panel (TRIGGER) is on “Normal” or “Single” and if the trigger level exceeds the waveform range. If yes, set the trigger level to the middle or set the MODE to “Auto”.

Note: using AUTO could automatically finish the above setting.

6. The display of waveform is ladder-like:

(1) The horizontal time base might be too low. Increase the horizontal time base to increase the horizontal resolution and improve the display.

(2) If Type is “Vectors”, the lines between the sample points may cause ladder-like display. Set Type to “Dots” to solve the problem.

7. Fail to connect PC or PictBridge through USB:

Check the IO Setting menu in Utility to make sure whether the setting in USB

Device matches the device currently connected. If needed, restart the oscilloscope.

8. The USB storage can not be recognized:

(1) Check if the USB storage can work normally.

(2) Make sure that the USB storage being used is flash type. This oscilloscope does not support hardware type USB storage.

(3) Make sure if the capacity of the USB storage is too large. It is recommended that the capacity of the USB storage being used with this oscilloscope is no larger than 8 GBytes.

(4) Restart the instrument and then insert the USB storage to check it.

(5) If the USB storage still can not be used normally, please contact RIGOL.
