Hey all,
I'm new to controllers but when I originally calibrated my PH probe I didn't realize that dipping the probe into ph 7.0 then into ph 9.0 without cleaning the probe would matter. And then after that I was recalibrating them again and someone recommended to dip the probe in freshwater before dipping into the calibration fluids so I did that as well.
Now I'm reading off of GHL's downloads that you are suppose to dry the probe before inserting into either calibration fluid. I believe my PH probe is reading a little low and was wondering if maybe the contamination of the fluids is the issue? I didn't think tiny amounts of the liquids would it affect it, but now I'm wondering if that's the reason for why my probe reads a bit low.
I know you can adjust the ph reading in GCC, but I don't have a reliable way to test my PH currently that I could use for the adjustment setting.
