Replacing the oxygen sensor

Replace the oxygen sensor when:

•The O2 channel cannot be set to 00.0% on an oxygen-free sample.

•The O2 display cannot be set to 20.9% by the Demand Zero command.

•The O2 reading drifts noticeably. For example, if the O2 reading varies from 20.5 to 21.5 while you view the display for a few seconds.

To replace the oxygen sensor:

1.Take the Eagle to a non-hazardous location, and turn the power off.

2.Unscrew the two large screws on the top of the case, then carefully lift the top of the case and lay it aside.

3.Locate the oxygen sensor. With the batteries closest to you, the oxygen sensor is at the bottom left corner of the sensor block.

4.Unplug the cable leading from the oxygen sensor at the large multi-pin connector.

5.Loosen the screws on the metal strap that covers the oxygen sensor.

6.Push the strap toward the screw that is furthest away from the battery compartment.

7.Swing the strap aside.

8.Remove the oxygen sensor.

9.Install the replacement sensor in reverse order.

Replacing the H2S or CO sensor

Replace the H2S or CO sensor when:

•The H2S or CO channel cannot be calibrated correctly.

•The H2S or CO reading cannot be set to 00 by the Demand Zero command.

NOTE: Allow up to 1/2 hour after you replace the H2S or CO sensor,

or if charged batteries have not been installed for an extended period, for the channel to show a normal response, then calibrate the sensor.
