Hello,
I am having some problems with my redox and salinity sensors. I am using p3 and have the sensors attached to the expansion box. My redox values began to drop drastically until it went into alarm. I don't see any reason why this would happen other than maybe the sensor needs recalibrated. So, I recalibrated the redox probe using 220mv solution. However, now after I recalibrate the redox probe, I continue to get a reading of only around 220mv. My values before were around 450mv. Also, I recalibrated my salinity probe and now I get values around 57.5ms. I used to get a reading of approx. 53ms.,...
I am just curious of what I am doing wrong and why the redox sensor values dropped in the first place. Do I need to reassign devices or sensors?? Help is very much appreciated because I would like to get this figured out.
Thanks,
Ben
