Difference between set pressure and blow-off pressure?
The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.

Because most modern tanks have a safety valve in them. If you open the valve too quickly, the valve will think that nothing is hoked to it and will shut off the output of the tank. Close the valve on the tank, dissconnect it from the regulator to let off the pressure and reset the check valve. Reconnect to the regulator and open the tank valve slowly..
Pressure switch adjustment?
