Being the delicate probe a pH probe is, I prefer not to stir with it.
I just swish my liquid in my beaker and gently lower the probe into it.

Thank you Gene. I am trying to figure out why I got 3 different readings in a
row. Tomato sauce, actually. I calibrated, tested. Recalibrated, tested.
Recalibrated, tested. Even if my pH 4 and pH 7 fluids were old, I'd expect
repeatability. Two place resolution, +/- .04 accuracy. I got 4.41, 4.16, and
4.30.
