I just received two new probes that read the ORP and PH for my pentair intellichem. It is not reading the PH correctly. It is incorrectly showing a PH of 8.8. We tested with our taylor TF100 and now its low at 6.8 because the machine just keeps dumping in the muriatic acid. How do I safely turn it off? The probes were replaced out of an abundance off caution because I incorrectly stored them over the winter inside my office without keeping them wet. The old probes were in fact spot on, and these new ones are giving bad readings. So frustrating. Its now screwing up the FC levels too...and on the hottest 2 days of the year. Any insight would be much appreciated.
