Help!! Redox and Salinity Sensor acting strange
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

Hi,
where are your sensors placed?

They are in the ghl probe cell container. This is where they have always been. Never had any issues before.

I do have Problems with my Redox probe as well!
After I had installed the new Firmware 5.16, I recalibrated the probe with 220mV solution (i tried it several times).
The vaules initially dropped down to 3mV after I placed the probe in the tank water, but now after a day, it reads 999mV??
The probe is also placed in the GHL cell Container.
Was there anything changed with the calibration process with the new Firmware??

My orp is now at 317 as of today.....it has been slowly rising again. Is this what happens when recalibrating probe?
