The PPM atmospheric dialog calculates the atmospheric ppm,
given the atmospheric pressure and temperature. If needed, the
ppm total value can be entered manually.
Call the dialog for PPM atmospheric settings from the Function
selection dialog.
Enter the atmospheric pressure and the temperature.
The ppm total value is computed, according to the “Barrel and
Sears” equation (see TPS1100 User Manual).
To accept the values and return to the dialog from which FNC has
been started.
Position the cursor bar on the ppm total value with the cursor key
and enter a new value. The values for Atm. pressure and
Temperature are deleted.
