RKI Instruments Eagle Series - Manual (Page 20)

13 • Operation Eagle Instruction Manual
based on Eagles in full response mode (methane elimination switch
set to CH4) calibrated to methane. Multiply the display reading by the
factor in the appropriate column in the table. For example, if you are
detecting hexane and the display reads 10% LEL, the actual hexane
reading is 10% x 2.14 = 21% LEL hexane.
WARNING: The Eagle’s alarms are initiated by the DISPLAY reading
not the FACTORED reading. If you are monitoring for
hexane as in the example above and the low alarm is set
for 10% LEL, the Eagle will initiate a low alarm at 21%
LEL hexane (display reading of 10% LEL).
To determine the concentration of other combustible gases with the
Eagle in methane elimination mode, see Table 7 on page 56.
