It is possible variant of your problem solution:

Danko, yes the simulation describes the issue and you know exactly what this is all about.
In case you are still active and interested, I was able to eliminate the phenomenon by using double frequency compensation. I did quite a lot research and testing on this (I was unable to find much existing theory about it). The unwanted capacitance in a solution correlates pretty well to the frequency and the rest is getting the math right.
So, in case you are still experimenting I wanted to let you know.

Yes, It will be very interesting to know your solution.

OK, I did return. And let me explain: The fact thatI do not understand a question, or even what is being asked, does not mean that I think it is a dumb question. It DOES mean that I do not understand it, and am asking for additional explanation. Many times others use totally different words to describe another aspect of something I do understand. THAT is why I ask! Eletro-Chemistry uses a language I don't speak, but instrumentation and measurement I may be able to help with.

 

Hello Mr. Bill,
No problem. I was electrodating (msg #12) without knowing it is very much unwanted approach in this community.

why do you give him such hard time because he didnt write what EC means. Just google it, there is literally one kind of EC sensor, and it aint European Community.

 

Consider that mostly, those folks who ask a question and pose that question with the needed details explained often get answers far sooner than those who pose questions requiring research effort to even know what they are asking about.
To translate that response more completely, if you hope to get an answer, pose the question with words that the people you are asking will understand.

 

" Just Google it "

NO, YOU just write it out completely, at least the first time it is mentioned in a Post,
and provide a Specification-Sheet, and/or, at least a picture or drawing,
or, at the very minimum, a verbal description of it's basic-function.

Why make people who are willing to help "jump through hoops" just to help You ?????

I find it happening in some technical publication, in some articles, where the assumption has been made that the only ones reading it are those totally familiar with all of the acronyms. But I read also articles about topics that I am not familiar with. How else will I learn about new topics?? And the article is full of strange acronyms, and seldom much of a clue as to what they even relate to.
