8. Troubleshooting
1. The oscilloscope cannot be turned on.
It may be that the battery is completely exhausted. At this time, even if the
oscilloscope is powered by the power adapter, the oscilloscope cannot be
turned on. You need to charge the battery first, and do not turn on the
oscilloscope. Wait for about 15 minutes, and then try to turn on the
oscilloscope. If the oscilloscope still cannot be turned on, please contact us to
serve you.
2. The oscilloscope turns off after a few seconds of startup.
It may be that the battery is exhausted. Check the battery symbol at the top
left of the screen. symbol indicates that the battery is exhausted and must
be charged.
3. After switching to the multimeter, the measurement type is displayed
as E.
It may be that the measurement type was not selected. At this time, press F4,
the measurement type should display the corresponding measurement type.
If E is still displayed, restart the oscilloscope.
4. In the oscilloscope state, the measured voltage amplitude value is 10
times larger or smaller than the actual value.
Check whether the channel attenuation coefficient is consistent with the
actual probe error ratio.
5. In the oscilloscope state, there is a waveform display, but it cannot be
stabilized.
⚫ Check whether the source item in the trigger mode menu is consistent
with the signal channel actually used.
⚫ Check whether the trigger electrical level has exceeded the waveform
range. Only by setting the parameters reasonably, the waveform can be
displayed stably.
6. In the oscilloscope state, nothing is displayed after pressing
