8. See “Chapter 3: Operation” on page 27 for instructions for start-up and operation of
the EAGLE 2.
9. While the charging module is powering the EAGLE 2, its amber LED will be off and
its green LED will be on.
Measuring Mode, Normal Operation
When the EAGLE 2 completes its startup sequence, it is in Measuring Mode. In
Measuring Mode the EAGLE 2 continuously monitors the sampled atmosphere and
displays the gas concentrations present for its target gases. In a low-light environment,
press and release any button to turn on the display backlight. See “Updating the Backlight
Delay Setting” on page 110 to program backlight duration. If the Confirmation Alert
feature is turned on in the Setup Mode menu (see “Updating the Confirmation Alert
Setting” on page 115), the EAGLE 2 beeps periodically to confirm that it’s operating.
Monitoring an Area
1. Start up the EAGLE 2 as described above in “Start Up” on page 27. 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 72
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
