CO2 to a maximum of 3.00% CO2, set the display to 2.00% CO2.

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 carbon dioxide sensor in the front half of the bottom case. A sensor with wires connected to EC3 on the analog PCB displays its reading on the third line of the screen. A sensor connected to EC4 on the analog PCB displays its reading on the fourth line of the screen.

4.Adjust the carbon dioxide sensor’s SPAN control one turn and observe the display reading. Continue to adjust the SPAN control until the display reading matches the concentration of the calibration cylinder.

The SPAN control is located on the top edge of the ampliﬁer and is the control closest to the front of the instrument. (The front of the instrument has the scrubber attached to it.)

5.Press the POWER/ENTER button to set the span value. SINGLE CALIBRATION END displays, then the Single Calibration menu displays.

6.Place the top of the case in its original position, then secure it with the large screws you loosened in step 5.

7.Disconnect the tubing from the probe.

8.Unscrew the regulator from the calibration cylinder.

9.With the Single Calibration menu displayed, press the SHIFT/▼ button until the prompt is next to the last channel, then press the SHIFT/▼ button again. The ESCAPE message displays.

10.Press the POWER/ENTER button to return to the Calibration menu.

11.Press the SHIFT/▼ button to place the prompt next to the NORMAL OPERATION menu option, then press the POWER/ENTER button to return to the normal screen.

Replacing Carbon Dioxide Sensors

Return the Eagle to RKI Instruments, Inc., for replacement of the carbon dioxide sensor when:

•The carbon dioxide channel cannot be calibrated correctly.

•The carbon dioxide reading cannot be set to zero by the Demand Zero command or zero potentiometer.
