284 • Leak Testing EAGLE 2 Operator’s Manual

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

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

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
