Conductivity problem
Since i installed the dimming parts and begun to use it i have had problems with the conductivity measurement, there has been a huge dip at lightning on and off.
After some investigation I have now found the problem, it’s the same problem i have had before when i tried to measure the pH with a regular computer, stray voltages.
I should have thought of that at once.
I found this problem by taking water from the aquarium into a plastic mug and placing the probe into that instead, then the problem disappeared, as did it do when i placed the probe and one hand in the aquarium and the other hand on the ground connection of a power outlet.
I found a pretty informative page on the subject which could be quite interesting to read:

I guess i will have to check up where to buy titanium now and create a ground probe.
