I have a Devillbis HVLP gun that says it should have 30 psi inlet pressure
for 10 psi at the spray cap. What's the best way set the inlet pressure?

I have an inlet gauge/regulator at the gun, is the 30 psi with the trigger pulled?
and then the pressure drop to the tip will result in 10 psi?

Thanks.
