2. Allow 2 minutes for the combustibles sensor to stabilize.

3. Perform the demand zero procedure as described in “Preparing

for Calibration” on page 41.

Monitoring combustible gases other than hexane

Use Table 7 to determine the concentration of combustible gases other

than hexane. This table is based on Eagle’s in methane elimination

mode (methane elimination switch set to HEX ON) and calibrated to

hexane. Multiply the display reading by the factor in the appropriate

column. For example, if you are using the Eagle to detect toluene and

the display reads 10% LEL, the actual toluene reading is 10% x 0.90 =

9% LEL toluene.

To determine the concentration of other combustible gases with the

Eagle in full response mode, see Table 4 on page 12.

WARNING: The Eagle’s alarms are initiated by the DISPLAY reading

not the FACTORED reading. If you are monitoring for

toluene as in the above example and the low alarm is set

for 10% LEL, the Eagle will initiate a low alarm at 9%

LEL toluene (display reading of 10% LEL).
