A few weeks ago I replaced my Intellichlor IC40. Seems to work fine (green lights, cell goes on), but when I bring my water samples in the pool store reading is always lower than what I get from the wall panel reading (about 500ppm lower). Is there anything can do to get the readings to better line up with the pool store readings? The store guys tell me to calibrate... but its a newer version (3.xx) and so it can't be calibrated (or so I have read).
