Many online say to turn the set screw 1/4 Of a turn counterclockwise. It I find it not to be very pricise. I use guages and compressed air. What I believe it most important though it is to know whether or not the valve is functioning correctly or even at all. Can't do that with just turning the screw. Unless you knew the valve was functioning fine before recalibrating it, turning the screw won't work and you wont know until after you have charged the system
