Bump Testing an Instrument with Special Sensors • 44
NOTE: If you have an EAGLE 2 with an IR CO
2
sensor in the 0-10,000 ppm or
0-5.00 %vol range, be sure to replace the air filter at the AIR inlet fitting
with the CO
2
scrubber when testing an instrument with a CO
2
sensor
installed to ensure that the CO
2
present in fresh air is scrubbed out.
Remove the black end caps from each end of the scrubber before
installing onto the AIR inlet fitting. Replace the caps when the scrubber
is not in use. See the “Spare Parts List” on page 80 for a scrubber with
a tubing stub.
11. Press and hold the BUMP
T
button until the BUMP
T
LED turns on (about
one second) then release it. The bump test begins. During the bump test, the
BUMP
T
LED will flash amber indicating that a bump test is in progress and
the EAGLE 2 display will show the current readings.
If you wish to cancel the bump test, press and hold the BUMP
T
button for at
least one second until CANCEL appears on the screen.
12. If at any point during the bump test the gas flow to the instrument becomes too
low, the bump test will be aborted and the screen will indicate a flow failure.
If a flow failure occurs, confirm all tubing connections are correct and that all
lines are clear.
• To return to the home screen, press and hold the EDIT ENTER button for

T
button.
