ph probe reading high, what values do I need to change?
Posted: Thu Dec 17, 2015 10:13 am
I have never got my ph probe to read properly. I gave up a few month ago, but I am going to give it another try.
I calibrated using ph 7 and ph 10. My test kit and my LFS ph meter have the same value, but my RA is consistently reading .4 high. I want to hardcode the ph.min and ph.max.
I am going to start with these values:
ReefAngel.PHMin=520;
ReefAngel.PHMax=840;
If I need to adjust it to raise the reading:
should my low go up or down?
should my high go up or down?
If I need to adjust it to lower the reading:
should my low go up or down?
should my high go up or down?
