8. Troubleshooting
This section addresses common issues you might encounter with your HANMATEK DOS1102 oscilloscope.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable not connected; Power adapter faulty; Power outlet issue | Check power cable connections; Try a different power outlet; Replace power adapter if necessary |
| No waveform displayed | Probe not connected; Input signal too small/large; Incorrect vertical/horizontal settings; Trigger not set correctly | Ensure probe is connected to signal source; Adjust vertical scale (Volts/Div); Adjust horizontal scale (Sec/Div); Use 'Auto-set' function; Adjust trigger level or mode |
| Unstable waveform | Improper trigger settings; Noise in signal | Adjust trigger level and mode (e.g., Edge, Video); Ensure proper grounding; Use averaging function if available |
| USB storage not working | U disk format incompatible; U disk capacity too large | Ensure U disk is FAT16 or FAT32 format; Use U disk with capacity up to 64GB |
