■
After the inspections above, restart the oscilloscope.
■
If the oscilloscope is still not used after the checking, please connect with our service centre.
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 the 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, please do the following steps:
■
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, please do the following steps:
■
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.
■
May be the display Type is set to “Vectors”, You could set it to Dots mode to improve the display.
