Monitoring an Area
1. Start up the EAGLE 2 as described above in “Start Up” on page 22. It is
now in Measuring Mode.
2. Take the EAGLE 2 to the monitoring area.
Put the probe tip in the area to be monitored.
NOTE: If the particle filter or hydrophobic filter become dirty or clogged,
replace them. If water enters the probe, dry out or replace the
particle filter (if installed) and shake any water out of the probe or
off of the hydrophobic filter. If you notice that water has entered the
flow system through the probe, replace the probe’s hydrophobic
filter and inspect the O-ring for filter particles. See “Replacing the
Hydrophobic Probe’s Particle Filter and Hydrophobic Filter Disk”
on page 75 for instructions to replace the particle filter and the
hydrophobic filter.
3. Wait 10 - 15 seconds and observe the display for gas readings. If a
reading is observed, allow the reading to stabilize to determine the gas
concentrations present.
NOTE: Response time increases with the length of the sample hose. Long
sample hoses will require more time to show a response at the
EAGLE 2. The maximum sample hose length recommended for the
EAGLE 2 is 125 feet. Consult RKI Instruments, Inc. for longer
sample hose lengths.
4. If a gas alarm occurs, take appropriate action. See “Responding to
Alarms” on page 38.
Using Optional Sample Hoses
The standard sample hose for the EAGLE 2 is 5 feet long. Optional hoses are
available up to 125 feet long. If you are considering using a longer hose, keep
in mind that a longer hose will increase the EAGLE 2’s response time and the
flowrate may decrease close to the low flow alarm point.
