EAGLE 2 Operator’s Manual Calibrating Using the Single Calibration Method • 99
In the example above, the EAGLE 2 could have adjusted the reading as
low as 11 %LEL and as high as 43 %LEL. Since the calibration gas value
entered was 50 %LEL, the unit failed the span adjustment. The buzzer
and alarm LED arrays activate in a double pulsing pattern. Press and
release the POWER ENTER RESET button to reset the alarm and return
to the Select Sensor Screen. Attempt to calibrate again. If the failure
continues, investigate the cause. See “Troubleshooting” on page 70
NOTE: The adjustment range will only appear in the calibration results
screen if the Span Factor item in Setup Mode is set to ON. If the
Span Factor is set to OFF, the adjustment range will not appear.
19. Disconnect the tubing from the EAGLE 2’s probe.
20. Repeat Step 6 through Step 19 for any other channels you want to
calibrate. Make sure you use an appropriate calibration cylinder for each
channel.
CAUTION: When calibrating the oxygen channel, verify the concentration
of oxygen listed on the cylinder’s label. For oxygen-free samples
(100% nitrogen for example), set the oxygen zero setting to
0.0%.
21. After the last channel is calibrated, disconnect the calibration tubing from
the probe.
22. With the Select Sensor Screen displayed, place the cursor next to
ESCAPE using the AIR ▲ YES button.
23. Press and release the POWER ENTER RESET button to return to the
Calibration Mode Screen.
24. Use the RANGE ▼ SHIFT button to place the cursor next to the
NORMAL OPERATION menu item, then press and release the
POWER ENTER RESET button to return to Measuring Mode.
