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 proceed as follows:
n
Vent the gauge to atmosphere
o
Unlock the user ATM Adjust wit a target value of "0"
p
Execute the User Atmosphere Adjust Service with a target value of "1".
The pressure value of the amtmosphere pressure sensor is then tracked to the
value of the Capacitance Diaphragm Gauge.
