Chapter 4 Troubleshooting
1. After the oscilloscopes is powered on, the screen remains dark (no
display):
(1) Check the power cord connection.
(2) Ensure the power switch is turned on.
(3) Check whether the fuse burns out or not.
(4) After the above inspection, restart the oscilloscope.
(5) If the problem still remains, please contact RIGOL for help.
2. After the signal acquisition the waveform does not appear:
(1) Check the probes connected with the signals.
(2) Check the probes connected to the channels firmly.
(3) Check the probes connected with the object being tested.
(4) Check the circuit generates signal at the test point (To judge whether channel or
determinand in question, you can input the probe compensation output signal
to a channel in question).
(5) Repeat the acquisition.
3. The measurement result is 10 times higher or lower than the value
expected.
Check if the probe attenuation is the same as the channel attenuation.
4. If the oscilloscope does not get a stable waveform display:
(1) Check the Trigger Source and notice if it is set to the channel in use.
(2) Check the Trigger Type. Use “Edge” for normal signals, and use “Video” for
VIDEO signals.
(3) Switch the coupling into LF Reject in order to filter out the low frequency noise
which disturbs the trigger or press HF Reject and select “ON” to filter out the
high frequency noise that disturbs the trigger.
(4) Adjust the trigger Sensitivity and the holdoff time.
5. After pressing the Run/Stop button, the oscilloscope does not display
any waveform on screen.
Check whether the Trigger Mode is set to “Normal” or “Single” and see
whether the trigger level is out of the signal range. If yes, set the trigger level in
proper range by turning the
knob or pressing the 50% button. Or set
the Trigger Mode as “AUTO”. Moreover, push Auto button to display the
