ph calibration - which numbers to use?

Post by rossbryant1956 »

what impact on my ph reporting will lowering the bottom number have? I got three numbers when I calibrated: 510, 539, 550. I am using 539 and my ph is reporting around 7.8. My testing says the ph is higher than that. I wondered what would happen if I change to one of the other numbers in my memory settings.

thx
