response level to the applied gas. This calculated range is independent of
the calibration gas value that was entered in Step 8 and Step 9 above. The
adjustment range is included on the result screen to indicate the condition
of the sensor. If the calibration gas value is in the adjustment range, the
span adjustment will pass. If the calibration gas value is out of the
adjustment range, the span adjustment will fail.
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 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.
13. Disconnect the tubing from the EAGLE 2’s probe.
14. Repeat Step 6 through Step 13 for any other channels you want to
calibrate. Make sure you use an appropriate calibration cylinder for each
sensor.
