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) After the above inspection, restart the oscilloscope.
(4) 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.
(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 HF Rejection or LF Rejection in
order to filter the noise which disturbs trigger.
(4) Adjust the trigger Sensitivity and the hold off time.
