Typical Applications where Pressure and Altitude are Used The Pressure screen will equal the Baro screen when the REF ALT on the Baro sub-menu is equal to zero (0). This measurement is displaying the station pressure at all times (there is no REF ALT input). Pressure Screen - The 4250 is the only Kestrel with a dedicated station pressure screen. Density Altitude is not related to the Altitude screen nor the REF ALT or REF BARO in any way. If the reference altitude is zero, then the Kestrel is displaying station pressure.ĭensity Altitude Screen - Shows you the current density altitude for your current location.
#DENSITY ALTITUDE UPDATE#
If the altitude is not reading correctly you most likely need to update the reference barometric pressure to the local, current barometric pressure.īaro Screen - the current pressure adjusted for sea level based on the reference altitude. If you turn Sync Alt OFF, the Kestrel will automatically turn Sync Baro to OFF and vice-versa.Īltitude Screen - Shows you current altitude based off of the pressure sensor and reference barometric pressure. PLEASE NOTE: If you turn Sync Alt ON, the Kestrel will automatically turn Sync Baro to ON and vice-versa.
If set to ON: When you adjust the REF ALT, the Kestrel will automatically update the REF BARO with the updated altitude value.Sync Alt - Found in the Barometric Pressure sub-menu (center button on Baro screen). If set to OFF: When you adjust the REF BARO, the Kestrel will not change the REF ALT value.
If set to ON: When you adjust the REF BARO, the Kestrel will automatically update the REF ALT with the updated barometric value.Sync Baro - Found in the Altitude sub-menu (center button on Alt screen). PLEASE NOTE: This value does not affect the density altitude (all models) or ballistic solution screen (ballistic models only). In this case, you would not have to adjust this reference value when changing altitudes. If you would like to know your station pressure, you would set the reference altitude to zero (0). As long as you do not change altitudes, the barometric pressure will remain correct. This value needs to be set to your current, local altitude in order for the barometric pressure to read correctly. Ref Alt - Found in the Barometric Pressure sub-menu (center button on Baro screen). PLEASE NOTE: This value does not affect the density altitude (all models) or ballistic solution screen (ballistic models only). If the atmospheric pressure changes, altitude will change even if unit did not change locations. This value needs to be set to your current, local barometric pressure in order for the altitude to read correctly. Stands for reference barometric pressure. Ref Baro - Found in the Altitude sub-menu (center button on Alt screen). Please note: Density Altitude will always read correctly on your Kestrel independent of your location or any reference values. In other words, it is the air density expressed as an altitude above sea level. When measuring pressure at sea level, station pressure and barometric pressure are equal.ĭensity Altitude - The altitude at which you would find the local air density, assuming standard atmospheric conditions (ISA). house, the top of a mountain, or on the shore).īarometric Pressure - The station pressure adjusted to mean sea level. Station Pressure - The pressure measured at a station, without any adjustment. Please note: Kestrels do not contain a GPS chip. GPS Altimeter - An instrument that determines your local altitude based on a GPS chip in the unit and satellites triangulating your location. Pressure Altimeter An instrument for determining elevation based on changes in air pressure. Auto Racing, Weather, Hikingīarometer - An instrument for measuring atmospheric pressure, used especially in weather forecasting.
