HDS2062M-N Handheld DSO & DMM                              8-Trouble Shooting 

8. Trouble Shooting 

1.

 

The oscilloscope does not power up   

It may be caused by the dead battery. At this time, the oscilloscope will not start even if it is 
powered by the battery charger. Firstly, charge the battery and supply the oscilloscope with 
power through the battery charger. However, don’t switch on the oscilloscope till waiting for 
15 minutes. If the oscilloscope still cannot start, please contact OWON for service.   

2.

 

The oscilloscope stops working only after operating for 

several seconds   

Probably the battery is dead; Check the battery symbol at the upper right of the screen. The   
symbol indicates that the battery has been run out of power and must be charged. 

3.

 

The measurement type displays ERR when you switch to 

the Multimeter mode.   

Probably you do not select the measuring mode. In this case, push down any key of the three 
keys V, A or R. Thus, the relative measuring mode will be shown on the screen. If the ERR is 
still displayed, restart the oscilloscope. 

4.

 

The measured voltage amplitude value is 10 times larger 

or smaller than the real value under the oscilloscope 

mode.   

Check whether the channel attenuation level matches the actual probe attenuation ratio.   

5.

 

The waveform is displayed on the screen but is not stable 

under the oscilloscope mode.   

z

 

Check whether the signal item in the trigger mode menu matches the actually used signal 

channel. 

z

 

Check on the trigger mode: The edge trigger mode is applicable to the universal single 

and the video trigger mode applicable to the video signal. Only when the proper trigger 
mode is applied, can the waveform be in stable.
