Conductivity Sensor Settings

[ingchr1]

Yesterday was a nice warm day here and our house temperature rose to ~80F. As expected, the temperature in our tank went up slightly above setpoint.

What I noticed when this happened is that the conductivity reading dropped (unexpected). I had temperature compensation set on Temperature 1.

With this setting I would have thought the conductivity reading would have been temperature compensated and would remain stable as temperature changes. I would have also thought that conductivity would increase with increased temperature.

What I did was change the temperature compensation to manual 25C, where I last calibrated the probe at. This change is reflected on the graph as the sharp increase in conductivity just after 9PM. This seams to have held a better reading, not affected by tank temperature.

Am I miss understanding the temeprature compenstation setting?

I’ve had sharp changes when my probe has gotten dirty. Try cleaning it and see if it steadies out.

It dropped slowly as temperature increased slowly.

The sharp increase is when I changed the temperature compensation from Temperature 1 to Manual.

After I changed it to Manual it remained steady, even as temperature slowly went back down to normal.
