First warning screen
Once the sensor calibration feature is selected, a warning message displays to in-
dicate that the 4-20 mA output should be disabled from any automatic control loop
to prevent false action during calibration. The user must acknowledge this screen
to continue. See  Fig. 27 for a view of this warning screen. Optionally, the user
may abort the process at this screen.
Second warning screen
After acknowledgement of the control loop message, a second warning message
displays, informing the user that sensor calibration will be changed. The user can
abort the procedure at this time or acknowledge the screen to proceed.  Fig. 29
for a view of this screen.
Zero Sensor function select screen
Upon acknowledgement of the calibration change warning screen, a calibration
function selection screen appears. To zero the sensor, select the “Sensor Zero”
function and acknowledge the screen.  Fig. 30 for a view of this screen.
Calibration initiated screen
Once a calibration selection function is selected, the command is sent to the device.
A status message is then returned to indicate the progress. The first status mes-
sage should indicate that the calibration sequence has started. This screen also
shows the sensor value, units and type information. No action is required as it is
only a five-second information screen and advances automatically. The user may
abort the process at this time.  Fig. 32 for a view of this screen.
Selection confirmation screen
After the initiating screen displays for five seconds, a second information screen
displays. This screen displays for five seconds and provides the user confirmation
of the current calibration selection. No action is required at this screen, but the user
may press the ABORT button to stop the process.  Fig. 34 for a view of this
screen.
