User Atmosphere
Adjust

Performs an Atmosphere Adjust for the ATM-
Sensor

There are no state transitions associated with the invocation of this service. It is,
therefore, incumbent upon the user to establish the device into the desired con-
figuration prior to, and during the execution of this service. This will generally in-
volve exposing the sensor to a known environment and treating the values read
during execution of the services accordingly.
A success service response indicates that the service was accepted and the ap-
plication process started.

To perform the User Atmosphere Adjust Request vent the gauge to atmosphere
and then start the User Atmosphere Adjust Service without any target value. The
pressure value of the atmospheric pressure sensor is then tracked to the value of
the CDG.
