Thanks! I thought of rechecking my stuff a Nth time yesterday and noticed the coupling too.
All is well in the world.

I'd be more worried by the fact that signal swings negative and not positive :-)
Don't worry though, it looks like you have the input coupling set to AC on the scope. Set it to DC and try again.
Hi all !
I have a montage where I use 16F628A I/P with the settings below. Due to the price that has increased a lot and the unavailability (is it an older generation?) I would like to switch to...
SOLVED: Had probes set on AC coupling instead of DC coupling. D'OH!
I am scanning an EC11 rotary encoder wired according to Bourns debounce design using a Owon SDS1104 scope:
R1 = 10K
R2 =...
The weird thing, it that the voltage can go above 5V and below 0V when I turn the encoder real fast.
I'm using USB voltage from the PC, so no idea how that happens. Maybe the scope loses it's...
(couldn't post all links in first post due to limit)
Turning it really fast and increasing scan speed has some attempts looking like these:

Re: Vevor SDS1104 4 channel scope
There's something hinky going on. Sometimes it won't scan the probes. I still haven't figured out what exactly.
Demon Yesterday, 22:09But I go though the MODES, eventually the RUN/STOP buttons goes red, I reset it...
