Appendix A: Bump Testing and Calibrating
EAGLE 2s with IR Sensors
The default gas port assignments for EAGLE 2s that have IR sensors installed are
different from EAGLE 2s without IR sensors and depend on the type of IR sensor.
Table 8 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 if the default assignment is not desireable. See “Setting the Gas Inlet
Parameters” on page 21 for instructions to change the gas port assignment.
NOTE: These default gas port assignments apply only to the SDM-E2 when
used in its Standalone Configuration. See the SDM-E2 PC Controlled
Configuration Operator’s Manual for a description of the PC Controller
Program’s default gas port assignments for IR sensors.
