had a little problem with over carbonating a beer in my fermenter.
hooked up the my pressure gauges to my "trusted" regulator and found that most of them are +/- 2 psi off.
are the 2 screws on the back of the gauges for calibrating?
if so how do you do about doing this?
(2 are liquid filled, 1 is not)
thanks
