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 m/s); The higher the wind speed, the less solar radiation induced error.

Barometric pressure readings are standardized to sea level. Elevation Range: -999’ to +15,000’; -600 to +4660 m. Note: The

console screen limits entry of lower elevation to -999’ when using feet as elevation unit. For elevations below -999’, use
meters.
