Select <2true> for airspeed calculated from differential pressure (Qc) taking into consideration altitude (Ps) and a user entered temperature value. Airspeed type: 1calibrated 2true If <2true> is selected, the default air temperature to be used in calculating airspeed must be entered. The display is: True airspeed default T: 15. 0 ºC 1. Entry field for default temperature to be used in true airspeed calculation. The default value is 15 ºC. Enter the default temperature value. This value can be edited when a true airspeed unit is selected in the [UNIT] menu. Changing this value changes the default temperature value for any true airspeed units that have already been setup. In RPM4-AD displays, calibrated airspeed units are represented in lower case (e. g. kts) and true airspeed units are represented in upper case (e. g. KTS). If <4user> is selected, the user unit must be defined. The display is: Define user unit: 1. 000000 unit/Pa 1. Entry field. Enter the number of user units per Pascal (Pa) in the entry field. Pressing [ENT] defines the user unit and returns to the <Set up unit #n> screen. The user defined unit label can be customized to any alphanumeric, four character label using the remote command "UDU" (see Section 4. 4. 4). See Section 7. 2 for information on the unit of measure conversions used by RPM4-AD. © 2005-2007 DH Instruments, a Fluke Company Page 72 3.
