Troubleshooting   

 
 

Errors in time scale   

  
When recording at short timebase (<1s/div) the sampling interval is <10ms. This is possible only on fast 
computers. Anyhow, do not execute other applications during the recording process, it may influence the 
measuring time scale.   
  
The timebase of the measurements is generated by the internal timer of the computer. This timer can be put 
on hold by other processes on the computer. This can cause a deviation in the time measurement.   
  
To ensure the precision of the time measurement at short timebase:   
  

  Use a fast computer.     

  Do not run other applications when recording     

  Use highest possible processor speed     

  Prevent your computer from going into sleep or power saving mode   

   
      
  

No signal   

  

  No communication with the computer (check that the cable is connected to the USB port).     

  If USB cable is connected, close the program. Disconnect and reconnect the USB cable and run the 

program again.    

 

o

  RUN button is not ON.     

o

  TIME/DIV switch is in the wrong setting, try 1s/div     

o

  Input amplitude is too large, adjust VOLTS/DIV setting.   

   
If the above tips have no effect, then test on a different computer or different USB port.   

Note

. Close the program before disconnecting the USB cable.
