Setting the Gas Inlet Parameters
The gas inlet parameters define what gas ports are used during bump testing or
calibration and lets you select the port for each channel in your instrument.
With the exception of the default settings outlined in “Appendix A: Bump Testing and
Calibrating EAGLE 2s with IR Sensors” on page 84, all of the standard 4 sensors
(catalytic LEL, O
2
, H
2
S, and CO) are assigned to GAS 1 and special sensors (PID,
TC, IR, and ESM-01) are assigned to GAS 2. When you change a gas inlet
assignment for a particular gas combination (for example, changing the gas inlet for a
high range PID channel to GAS 1 so that a 5-gas cylinder can be utilized), the SDM-
E2 will remember the gas inlet setting for other EAGLE 2s with the same gas
combination. The SDM-E2 will remember the gas inlet setting for 10 EAGLE 2 gas
combinations. When an 11th gas combination is connected, the 1st gas
combination’s gas inlet settings will be discarded.
Do the following to set the gas inlet parameters.
1. Turn on the SDM-E2 with an EAGLE 2 and establish a connection between
them as described above in "Turning on the SDM-E2 with an EAGLE 2". The
EAGLE 2 will display the home screen.
2. Press and hold the EDIT ENTER button for 2 seconds. The EAGLE 2 will
display the Edit Mode screen.
