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
