I have never seen instructions to have your gauge calibrated for
altitude. The BBB does have instructions for the proper pressure for
different altitudes. For example, if the recipe calls for 11 psi at
sea level, you would need to reach 15 psi at 10,000 feet for the
internal temperature to reach 240°F.
