7. F.A.Q

1. In the case of that the oscilloscope is still in the black-screen state without any
display after the power is switch on, implement the following fault treatment
procedure.
Check whether the power connection is connected properly.
Check whether the power switch is pushed down to the designated position.
Check whether the fuse which is beside the
can be pried open with a screwdriver).
Restart the instrument after completing the checks above.
If this product still can not work normally, please get in touch with Lilliput and
we will be under your service.
2. After acquiring the signal, carry out the following operations if the waveform of
the signal is not displayed in the screen.
Check whether the probe is properly connected to the signal connecting wire.
Check whether the signal connecting wire is correctly connected to the BNC
(namely, the channel connector).
Check whether the probe is properly connected with the object to be measured.
Check whether there is any signal generated from the object to be measured (the
trouble can be shot by the connection of the channel from which there is a signal
generated with the channel in fault).
Make the signal acquisition operation again.
3. The measured voltage amplitude value is 10 times greater or smaller than the
actual value.
Check whether the channel attenuation coefficient and the attenuation ration of the
probe used in practical application is match (see "How to Set the Probe Attenuation
Coefficient" on P14).
4. There is waveform displayed, but it is not stable.
Check whether the Source item in the TRIG MODE menu is in conformity with
the signal channel used in the practical application.
Check on the trigger Type item: The common signal chooses the Edge trigger
mode for Type and the video signal the Video. If Alternate trigger is selected,
both of the channel 1 and channel 2 trigger levels should be adjusted to the
proper position. Only if a proper trigger mode is applied, the waveform can be
displayed steadily.
Try to change the trigger coupling into the high frequency suppress and the low
frequency suppress to smooth the high frequency or low frequency noise
triggered by the interference.
5. No Display Responses to the Push-down of Run/Stop.
Check whether Normal or Signal is chosen for Polarity in the TRIG MODE menu and
the trigger level exceeds the waveform range.
If it is, make the trigger level is centered in the screen or set the trigger mode as Auto.
In addition, with the Autoset button pressed, the setting above can be completed
automatically.
