Note:
Troubleshooting
The commonly encountered failures and their solutions are listed below. When you encounter those problems, please
solve them following the corresponding steps. If the problem remains still, please contact BK Precision.
The screen is still dark (no display) after power on
1.
Check whether the power is correctly connected.
2.
Check whether the power switch is really on.
3.
Check whether the fuse is burned out. If the fuse needs to be changed, please use the specified fuse.
4.
Restart the instrument after finishing the above inspections.
5.
If it still does not work correctly, please contact BK Precision.
The signal is sampled but no waveform of the signal is displayed
1.
Check whether the probe is correctly connected to the signal connecting wire.
2.
Check whether the signal connecting wire is correctly connected to the BNC (namely channel connector).
3.
Check whether the probe is correctly connected to the item to be tested.
4.
Check whether there are signals generated from the item to be tested (you can connect the probe compensation signal
to the problematic channel to determine which has problem, the channel or the item to be tested).
5.
Resample the signal.
The tested voltage amplitude is greater or lower than the actual value
Check whether the attenuation coefficient of the channel complies with the attenuation ratio of the probe.
This problem usually occurs when probe is used.
There is waveform display but not stable
1.
Check the trigger signal source: check whether the
Source
item at the trigger panel complies with the signal channel
actually used.
2.
Check the trigger type: general signals should use
“Edge”
trigger and video signal should use
“Video”
trigger. Only
when the proper trigger type is used, can the waveform be displayed stably.
3.
Change the trigger holdoff setting.
