There's something hinky going on. Sometimes it won't scan the probes. I still haven't figured out what exactly.
But I go though the MODES, eventually the RUN/STOP buttons goes red, I reset it...
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...
Re: Vevor SDS1104 4 channel scope
If you don't know, read up on what Auto/Normal/Single mode actually does. Also, there's no indication of trigger level on the scope screen, where do you have that set?
