connected and select Inert Mode. To use the EAGLE 2 in Normal Mode, select
Normal Mode and refer to “Measuring Mode, Normal Operation” on page 33. If you
have not made a selection after 20 seconds, the instrument will begin to beep and the
LEDs will begin to flash. They will continue until you make a selection.
WARNING:
The EAGLE 2 is not a gas monitoring device until you select a mode
and enter it.
6. The warm up sequence will continue as described in “Start Up” on page 27. The
oxygen alarms in the alarm point screens will be the alarm points for Inert Mode and
not for Normal Mode.
7. When the warm up is complete and the instrument is operating in Inert Mode, the
screen will appear as shown below if the instrument is sampling a fresh air
environment. The screen is shown with %LEL and oxygen channels. Your unit may
only have %LEL.
If the instrument is sampling a fresh air environment, the oxygen channel will be in
alarm.
For more information about Inert Mode, see “Appendix N: Using the
EAGLE 2 in Inert Mode” on page 261.
8. When monitoring for combustible gas in an inerted tank, be sure the dilution fitting is
installed and multiply the combustible gas reading by 2.
When monitoring for oxygen in an inerted tank, remove the dilution fitting or seal the
dilution hole with your finger.
Alarms
The EAGLE 2 Tank Tester model has two sets of oxygen alarm settings, one for Normal
Mode and one for Inert Mode. The Inert Mode oxygen alarms are factory-set at 5.0% by
volume (rising) and 10.0% by volume (rising). Normal Mode oxygen alarm setpoints also
exist and take effect when you select Normal Mode at start up.
The
rising
Inert Mode alarms are used to monitor a purged vessel to alert you to a rising
oxygen condition.
The oxygen level in a fresh air environment is above both Inert Mode oxygen alarm points
so the EAGLE 2 Tank Tester version
will
go into alarm when turned on in Inert Mode in a
fresh air environment. To silence the alarm, press the RESET button. The audible alarm
silences, but the alarm lights continue to flash and the display screen continues to indicate
an oxygen alarm. If one of the alarm levels is newly exceeded, the audible alarm sounds
again.
For information about viewing and changing the standard alarms used in Normal Mode,
see “Updating the Alarm Point Settings” on page 106. For information about viewing and
changing Inert Mode oxygen alarms, see “Appendix N: Using the EAGLE 2 in Inert
