catalytic combustible channel.
You can select from a list of gases whose response relative to the configured
gas, normally methane, is programmed into the EAGLE 2’s memory. This
includes several pre-defined gases and 5 gases that can be entered into the
EAGLE 2 in the field using the Eagle 2 Maintenance Data Loader Program.
In order to program a field defined gas into the EAGLE 2, gas testing must be
performed to determine the gas’ response factor relative to methane. See the
Eagle 2 Maintenance Data Loader Program Operator’s manual for details
regarding the gas testing and programming user defined gases into the
EAGLE 2’s relative response list. The last five items in the gas list are
reserved for field defined gases.
The relative response feature enables you to temporarily monitor for the
selected gas without having to recalibrate the EAGLE 2. The EAGLE 2 will
clear the gas configuration change when it is turned off and will return to the
programmed configuration when it is turned on again.
Because of normal variation between sensors, these relative response factors
are typical factors. If you use this feature, the response to the selected gas will
not be as accurate as it would be if you configured and calibrated the catalytic
combustible channel to the target gas.
NOTE: For maximum accuracy, configure and calibrate the EAGLE 2’s
catalytic combustible channel to the desired target gas.
