Appendix J: Methane Elimination Mode
Overview
For applications where methane is an interfering gas, you can set the EAGLE
2 to eliminate most response to methane using methane elimination mode.
CAUTION: The EAGLE 2 catalytic combustible sensor experiences a
significant gas response drop when it is changed from full
response mode to methane elimination mode. The EAGLE 2
must be calibrated in both full response mode and in methane
elimination mode to account for this. See “Calibration” on
page 269 for further instructions.
Monitoring in Methane Elimination Mode
To monitor an area using methane elimination mode, do the following:
1. Turn on the EAGLE 2 as described in “Start Up” on page 22.
2. Make sure that the EAGLE 2 catalytic combustible channel is set to
monitor a gas in which methane elimination is an option. For a list of
these gases and a procedure to select one, see “Configuring the
Combustible Gas” on page 108. A common target gas is hexane. Once a
gas that allows for methane elimination is selected for the catalytic
combustible channel, the methane elimination mode screen becomes part
of Display Mode.
3. Use the DISPLAY button to enter Display Mode and to scroll through the
screens until you reach the Methane Elimination Mode screen. The
current setting is displayed.
4. Press and release the AIR ▲ YES or RANGE ▼ SHIFT button to toggle
the setting to ENABLED.
5. Press and release the POWER ENTER RESET button. The unit will save
the setting and proceed to the next menu item.
