  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.
