| Problem with rigol scope knob |
| << < (5/9) > >> |
| M.Hassem:
If you can find a good replacement, from a mechanical point of view (it fits the original place), you might try using an optical encoder with the same output as the mechanical one these things have. Optical encoders last more and are more reliable. But they're a hell of a lot more expensive! |
| sonicj:
i wonder if someone forgot to debounce that encoder? -sj |
| Simon:
a possibility except that these faults seem to occur after some time, if there was a lack of debouncing then it would happen since day one ? |
| sonicj:
might be that a factory fresh encoder doesn't reveal the debounce oversight, but as the encoder breaks in, loosens up, grease gets pushed aside, etc. a contact bounce can occur. -sj |
| Simon:
right so the bouncing issue is down to failure of the mechanics of the switch/knob |
