6.4 Applications
6.4.1 Measure Application
The Measure App is the normal operation screen referred to in previous instruments as the
‘main screen’. This application is different from the others in that it is not use to setup the con-
figuration but is used to monitor the pressure (altitude and/or airspeed) applied to the installed
transducers.
The screen in figure 6.4.1-A shows the basic Measure App in Air data (Ps/Qc) mode. The units button is
always present in each channel. When the units button is pressed on the Ps channel a selection of feet
or meters plus a button for the selection of imperial and metric units will be displayed on the right (figure
6.4.1-B); notice that the Units button has a lighter background when the selection menu is active. When
the units button is pressed on the Qc Channel a selection of Knots, MPH, Km/hr and m/s is displayed,
plus the same selection of imperial or metric units. If a barometric reference is installed, the barometric
pressure will be displayed in the lower right hand corner of the screen.
