From what I see on the forums the Pentair intellichlor more recent models beyond version 1.9 can not be field calibrated. Mine is ver 3.1.
My IC 40 is reading 4100PPM, But my test strips read about 3200PPM. (should be about 3200 based on the amount of salt I added)
The cell is clean.
Has anyone come across a way to field calibrate the newer models?
I read a post that said for every degree above 77 salt level may read elevated by 100 PPM. Is this true ? If so, It is consistent because I keep my pool at about 88.
I am in a good working range now, but if the salt drops over the season and it is reading high, there could be less than ideal salt while the unit is running. Would this damage the unit?
