Sample Calibration Procedure

This procedure will vary according to the type of sensor connected to the
XNX Universal Transmitter.
1. Connect the sensor to the XNX transmitter.
2. Connect the Foundation Fieldbus handheld unit and establish
communication with the XNX transmitter.
3. Navigate to the Device Calibration menu on the Foundation Fieldbus
user interface.
4. Check the calibration status. The "In Calibration Menu State"
message will be displayed.
5. Select "Start Calibration." A window with the message "Processing
Request" will be displayed, followed by "Calibration Status. Apply
Zero Air."
6. Select "Finish." The window will close and the calibration status will
change to "Apply Zero Air."
7. Apply zero (ambient) air to the sensor.
8. Select "Next Step." A window with the message "Processing Request"
will appear, followed by "Wait until raw conc. is stable and in range."
9. Select "Finish." The window will close. and the calibration status
will change to "Wait until raw conc. is stable and in range." The raw
concentration will be near 0.0000. The input range will be "in range."
10. Select "Next step. The message "Processing request" will be
displayed followed by "Press NEXT to Start Zero Calibration."
11. Select "NEXT." A window with the message "Processing Request" will
be displayed, followed by "Calibration status: Processing calibration."
12. Select "Finish." The window will close and the calibration status will
display "Processing calibration."
13. If the zero calibration is unsuccessful, the calibration status will
change to "Zero Cal Failed. Press End Cal and Start Over. Proceed
to step 23 to end the calibration and start a new one. If the zero
calibration is completed successfully, the calibration status will
change to "Zero Cal Success. Press Next Step." Select "Next Step."
A "Processing Request" message will be displayed, followed by
"Calibration Status: Apply Target Concentration."
14. Select "Next."
