15. The EAGLE 2 is now operating in Leak Check Mode. The pump is
on and the following screen appears.
NOTE: For maximum sensor stability, allow 3-5 minutes for the sensor to
warm up. The small increment size in the lower range of a ppm
measurement can cause instability if the unit is not properly warmed
up.
Performing a Demand Zero, Leak Check Mode
Before using the EAGLE 2, it is recommended to set the fresh air reading for
the target gas by performing a demand zero. This will set the CH
4
channel to
zero.
1. Find a fresh-air environment. This is an environment free of toxic
or combustible gases and of normal oxygen content (20.9%).
2. Turn on the unit as described above in “Turning On the EAGLE 2,
Leak Check Mode”.
3. Press and hold the AIR ▲ YES button. The display prompts you to
hold the AIR ▲ YES button.
4. Continue to hold the AIR ▲ YES button until the display prompts
you to release it. The EAGLE 2 will set the fresh air reading for the
CH
4
channel. Start up is complete and the unit is now ready for
monitoring.
Leak Testing
In Leak Check Mode, the EAGLE 2 only displays combustible gas readings.
The readings are displayed in both numerical and bar graph form. The bar
graph displays readings up to 5,000 ppm while the numerical indicator
displays readings up to 50,000 ppm in the following increments:
• 5 ppm increments from 0 ppm to 200 ppm
• 10 ppm increments from 200 ppm to 1,000 ppm
• 50 ppm increments from 1,000 ppm to 10,000 ppm
