Normal Operation of Carbon Dioxide Sensors

Carbon dioxide is a background gas in fresh air. Table 11 indicates typical gas readings for each of the Eagle’s carbon dioxide sensors.

Demand Zero for Carbon Dioxide Sensors

When setting the zero reading, the carbon dioxide scrubber mounted to the front of the Eagle allows you to eliminate carbon dioxide normally found in fresh air.

NOTE: When performing a demand zero with a 0 - 20% or 0 - 50% CO2 unit, the use of a scrubber is not required.

1.Connect the carbon dioxide scrubber directly to the Eagle’s inlet fitting.

2.Wait one minute for the fresh air sample to flow through the carbon dioxide scrubber, then press the AIR/▲ button to set the zero reading.

If the carbon dioxide sensor fails when you press the AIR/▲ button, use the zero control (marked F. ZERO) on the amplifier to adjust the reading to zero.

CAUTION:Do not adjust the coarse zero potentiometer (marked C.ZERO).

3. Remove the tubing from the carbon dioxide scrubber and probe.

Calibrating Carbon Dioxide Sensors

Recommended calibration frequency for carbon dioxide sensors is once every 3 months. Enter Calibration mode and calibrate carbon dioxide sensors as described in the Calibration section of this manual. Use the Auto Calibration method if a calibration cylinder is available that includes all target gases for your Eagle. Use the Single Calibration method if you are using a carbon dioxide calibration cylinder.
