2.2.2 Step 2 – Calibrate the Unit
All units are calibrated at the Neutronics factory before shipping. However, it is recommended that
the model 1100 be calibrated at commissioning, under ambient and process conditions similar to
those encountered while in-service. Refer to section 3.2.1 for detailed analyzer calibration
instructions.
Helpful hint: The model 1100 is configured-to-order, as specified by the user per the application. If
the application has changed, some adjustments in the system configuration may be necessary to
optimize the model 1100 performance for the application. After reviewing the calibration
instructions, review Appendix C – Factory Configuration Settings. Verify that the current settings
are suitable for the application. Refer to Appendices E and F for all valid range and output settings
available on the model 1100. If any changes are necessary, they can be performed via the control
panel (section 4.1.1) or the service port (section 4.1.2).
2.2.3 Step 3 –Set Alarm-1 and Alarm-2
After the unit has been calibrated on a known gas source, set the alarm points according to
process control requirements. Refer to Appendix C for factory settings.
2.2.3.1 Set Alarm-1
For process control applications, alarm-1 is used normally as the “primary” oxygen-level alarm, and
is set to the highest or lowest level of oxygen allowable in your process, according to the
application. Refer to section 3.2.2 for information about setting the alarm-1 level.
2.2.3.2 Set Alarm-2
For process control applications, alarm-2 is used normally as the “secondary”, or “warning”
oxygen-level alarm, and is set just below to the highest, or just above the lowest level of oxygen
allowable in your process, according to the application. Refer to section 3.2.3 for information about
setting the alarm-2 level.
