4.2 Troubleshooting
1. After the oscilloscope is powered on，the screen remains dark ，
please do as following steps：
●
Check
the power cable's connection.
●
Ensure
the power switch is turned on.
●
After
the inspections above，restart the oscilloscope.
●
If
the oscilloscope is still not used after the checking, please connect with
MY company
2. If there is no signal wave in the screen after gathering the signal, please
do as following steps:
●
Check
the probe connecting with the signal cable or not
●
Check
the signal cable connecting with the BNC connector or not.
●
Check
the probe whether connect with the goods tested or not.
●
Check
the tested goods produce the signal or not.
●
Gather
the signal again.
3. The value of the tested voltage is 10 times higher/lower than the real one ,
please do as following steps:
Check the attenuation quotient whether match the probe attenuation proportion
or not.
4. Display the wave, but not steady , please do as following steps:
●
Check
the signal source on the trigger interface whether or not matches the
signal channel.
●
Check
the trigger mode: normal signal should use the edge trigger mode.
The video signal should use the Video Trigger mode. The signal would
display steady, only using the matching trigger mode.
●
Attempt
to change the coupling into HF Reject or LF Reject display, so
that the High/low frequency noise disturb the trigger should be filtrated
5. Press RUN/STOP button, but no display.
Check the trigger mode on the trigger interface whether or not in the normal
or single, and check the trigger level is whether or not over the wave range.
If yes, please put the trigger level to the middle position or set the trigger mode
to the Auto position. In another hand, you could choose the Auto button to set
up automatically.
6. After the Acquisition is set to Averages or Display Persistence time is set
too long, the waveform refreshes slowly.
It is normal in these settings
7. The signal is displayed as ladder like waveform
●
This
phenomenon is normal. The time base maybe is too slow .you should
turn the horizontal SCALE knob to increase horizontal resolution to improve
the display.
●
Maybe
the display Type is set to Vectors, You could set it to Dots mode to
improve the display.
■ USB Flash Drive isn't connected! : When the Save To option is set to File
or the Print Key option is set to Save Picture in Save/Recall menu , Press
the Save option button or the S/div knob before inverting the USB Flash
Drive to the USB Host port will appear this information on the screen.
■ Record Wave Success! : This message will appear when you finish recording
waveforms.
