A : The application requires a safety limitation to a maximum of 6 psi, to avoid over-pressurizing the aircraft system.
That’s why the air regulator is limited to 6 psi, and why we’ve added a 6 psi relief valve.
The pressure gauges available on the market are 10psi gauges. They have their own accuracy, which is a % of their full scale (0-10psi). We must therefore refer to this full scale (0-10psi) when determining accuracy.
