Barometric pressure readings are standardized to sea level. Elevation Range: -999’ to +15,000’;

 -600 to + 4570 m. Note: The console screen limits display of lower elevation to -999’ when using feet 
as elevation unit. For elevations lower than -999’, use meters.

This is the reduced value after standardizing to sea level.
