The Test Tools Does Not Start Up
|
The batteries may be completely empty. In this case the test tool will not start up, even if it is powered by the battery charger. Charge the batteries first: power the test tool with the battery charger without turning it on. Wait about 15 minutes and try turning on the test tool again. If it still can not start up,please contact with the owon service. |

The Test Tool Shuts Down After A Few Seconds
|
The batteries may be empty. Check the battery symbol at the top right of the screen. A symbol indicates that the batteries are empty 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 and 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 actual one under the oscilloscope mode. |
Check whether the channel attenuation factor matches the actual probe error ratio. |
| 5 |
The waveform is displayed on the screen but is not stable under the oscilloscope mode. |
▲Check whether the signal item in the trigger mode menu matches the actually used signal channel.
▲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.
▲Try to change the trigger coupling into the HF repression and LF repression to filter the HF or LF noise trigger by the interference. |
| 6 |
There is no display on the screen when you push down RUN/STOP key under the oscilloscope mode. |
▲Check whether the trigger mode in the trigger mode menu is in normal or single shot and whether the trigger level is out of the waveform range.
▲In such condition, adjust and make the trigger level in the middle or select the non-auto trigger mode. Additionally, press the AUTO SET key and complete the above setting |
| 7 |
When select the average sampling in the sampling mode or select a longer display time in the display mode under the oscilloscope , the display speed is slow. |
It is normal in the above case. |
