I recently replaced my orp sensor. Now my orp constantly reads low, disagreeing with my chemical tests. Orp is reading around 400 and FCU is greater than 15 and cc is 0. Is there a calibration/replacement procedure to correct this?

The calibration (tweak) is (+/- 50mV) since you are out of the range to adjust, you may need to replace this or exchange it with your dealer, you may also want to check the date code on the sensor as well, they do have a shelf life, you may contact us at 1-800-831-7133 for further assistance.
