I am having issue with one of my DO probe signals. In the last day it has gone from being a nice and smooth signal (like the one on the left) to the one on the right.
There has not been any program changes, I have changed instrument membrane/electrolyte solution, checked connection interface and recalibrated but still didn't help.
How do I get it back to a smoother signal?
Who wrote the program? Are you really running this in "continuous run" mode? Why???
Both windows show several signals, which is correct (e.g. are you comparing yellow and green?)? What is a "DO probe signal"?
(This seems like a hardware problem, so it is not clear why you would add to a existing discussion that is several months old. You really need to be much more specific. What's the hardware? How are things connected? What is the experiment?)
