Appendix B: Bump Testing and Calibrating EAGLE 2s
with IR Sensors
The default gas port assignments for EAGLE 2s that have IR sensors installed
depend on the type of IR sensor. Table 9 below outlines the default gas port
assignments for various typical sensor combinations. The gas combinations listed
under the “Multiple IR Sensors” section are listed as the channels appear on the
screen. The gas port assignments can be changed during bump testing or calibration
if the default assignment is not desireable. See “Bump Testing an Instrument with
Special Sensors” on page 71 and “Calibrating an Instrument with Special Sensors” on
page 87 for instructions to change the gas port assignment.
NOTE: These default gas port assignments apply only to the SDM-E2 when
used in its PC Controlled Configuration. See the SDM-E2 Standalone
Configuration Operator’s Manual for a description of the Standalone
Configuration’s default gas port assignments for IR sensors.
