EAGLE 2 Operator’s Manual
Calibrating Using the Single Calibration Method • 93
18. If the span adjustment is successful, the following screens display.
In the example above, the EAGLE 2 could have adjusted the reading as low as 35
%LEL and as high as 98 %LEL.
If the span adjustment is not successful, a screen displays that indicates a calibration
failure.
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 67.
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.
