110 • Using Setup Mode EAGLE 2 Operator’s Manual
WARNING: Do not configure the catalytic sensor gas to hydrogen if you
are monitoring for general hydrocarbons. Only use this
selection if you are monitoring exclusively for hydrogen or if
you do not want to see a significant response to other
combustible gases.
• 18000 ppm IBU
This selection is for isobutane. The LEL for isobutane is 1.8%, or
18,000 ppm. If the gas is configured for this choice, the methane
elimination feature is inactive and the Methane Elimination Mode
Screen will not appear in Display Mode. See “Methane Elimination
Mode Screen” on page 43 for a description of the Methane
Elimination Mode Screen. See “Appendix J: Methane Elimination
Mode” for a description of Methane Elimination Mode.
• 50000 ppm GAS
This selection is for a generic combustible gas with the LEL set to
50000 ppm. If the gas is configured for this choice, the methane
elimination feature will be active, but the Methane Elimination Mode
Screen will not appear in Display Mode, so methane elimination
cannot be turned off. In addition, the relative response feature is
inactive even if it is set to ON in the Setup Mode Relative Responses
menu item.
CAUTION: The 50000 ppm GAS gas configuration is normally set at the
factory for very specific applications. Consult RKI Instruments,
Inc. before configuring the gas for 50000 ppm GAS.
• 50000 ppm CAT
This selection is for users who want their catalytic channel to be
configured with the standard factory settings but would like the gas
name to be displayed as something other than CH
4
so that it doesn’t
get confused with other combustible sensors that might be installed
(IR, TC). The LEL is set to 50,000 ppm. If the gas is configured for
this choice, the methane elimination feature is inactive and the
Methane Elimination Mode Screen will not appear in Display Mode.
See “Methane Elimination Mode Screen” on page 43 for a
description of the Methane Elimination Mode Screen. See “Appendix
J: Methane Elimination Mode” for a description of Methane
Elimination Mode.
