Outside temperature accuracy is based on the temperature sensor itself and not on the sensor and the passive shielding 

together. The solar radiation induced error for the radiation shield: +4

F (2C) at solar noon with the wind speed at less than 

or equal to 2 mph (1 ms); The higher the wind speed, the less solar radiation induced error.

**

Barometric pressure readings are standardized to sea level. Elevation Range: -1500’ to +15,300’; -430 to

+4660 m. Note: The console screen limits display of lower elevation to -999’ when using feet as elevation unit. 

***

This is the reduced value after standardizing to sea level.
