The P4 is working amazing right now and I am just finishing up programming and messing around with things.
I am however having a issue with the PH probe and Redox Probe.
My PH swings from 10.50 to 4.0? When I calibrate in the 7.0-9.0 if I leave the probe in the 9.0 lets say it drifts all over the place 9.5, 8.5, 9.3 and so on.
As for the Redox it reads -200 then when calibrated reads 1000..
I assume I am doing something wrong but have calibrated a few time now with the same results... Any ideas?
Temp and Salinity working great.
