Troubleshooting
The most common problems and their solutions are listed below. When you encounter these problems,
please follow the steps below. If the problem remains still, please contact Electro Static Technology .
1.
The screen is still dark (no display) after powering on:
1)
Check whether the power switch was actually switched on.
2)
Check whether the power and/or battery are correctly connected.
3)
Restart the instrument after finishing the above inspections.
2.
The signal is sampled but no waveform of the signal is displayed:
1)
Check whether the probe is correctly connected to the cable.
2)
Check whether the cable is correctly connected to the BNC (namely channel connector).
3)
Check whether the probe is correctly connected to the system be tested.
4)
Check whether probe receives the 1 kHz signal from the compensation output terminal (this
will tell you whether the problem is in the probe/scope or the tested system)
5)
Check whether there is signal generated from the test system.
6)
Resample the signal.
3.
The tested voltage amplitude is greater or lower than the actual/expected amplitude:
Check whether the attenuation coefficient of the channel complies with the attenuation ratio of the
probe. If for example the probe is set to 10X, the channel must also be set to 10X.
4.
There is waveform display but not stable:
1)
Check the trigger signal source: check whether the
Source
item at the trigger panel is the
channel you are trying to measure on.
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.
5.
No display after pressing Run/Stop:
Check whether the mode at the trigger panel (TRIGGER) is on “Normal” or “Single” and whether the
trigger level exceeds the waveform range. If yes, set the trigger level to the middle or set the mode
to “Auto”.
Note
: using
AUTO
could automatically finish the above setting.
