Thank you for the Add.
So, last night I calibrated my Conductivity probe... I followed the directions to the letter. When done, my reading was 34.9! Great... I removed it from the solution and put it into my sump. Away from any interference. It jumped to 54/55... Thought that's weird but maybe I have some stray voltage... so I routed the probe cable 2 feet from any power wire and filled a beaker with water, separate from the tank water to see if I did have stray voltage in the tank... it still read 55. As the water cooled it dropped to 50. Back in the solution 35. I have the temp probe on the PM2 also calibrated and offset at 2.2 for salinity calibration ... now what?
