26. Connect the tubing from the demand flow regulator to the rigid tube on the probe.
Allow the EAGLE 2 to draw gas for one minute.
27. Press and release the POWER ENTER RESET button to set the span adjustment for
each channel to the programmed values.
28. If all channels passed calibration, the following screen sequence occurs.
If any of the sensors cannot be adjusted to the proper value, a screen displays that
indicates a calibration failure and lists the sensor(s) that failed to calibrate. In the
example below, the oxygen and H
2
S channels failed calibration. The other sensors
calibrated normally.
The buzzer and alarm LEDs activate in a double pulsing pattern. Press and release the
POWER ENTER RESET button to reset the alarm and continue to the Calibration
Value Screen for the infrared hydrocarbon channel. After calibrating the infrared
hydrocarbon channel by following the instructions below, attempt to calibrate the
standard channels again. If the failure continues, investigate the cause. See
