IRGASON Integrated CO

O Open-Path Gas Analyzer and 3D Sonic Anemometer

rubber seals on the ends of the shroud are clean and in good condition.

Position one end of the shroud over the lower snout and twist the top part

of the shroud, allowing it to extend and cover the upper snout; while doing

so, avoid making contact with the sonic transducers. Continue twisting the

shroud until it is fully extended and covering both snouts. Twist the

shroud so that the gas tubes and temperature thermistor cable are directed

towards the back of the sensor. Hang the tubes and cable over the trunk of

the sensor to alleviate any strain on the optical arms. See Figure 9-3, The

zero-and-span shroud mounted on the zero-and-span stand.

span stand. The top tube is the gas intake, the black cable is the

temperature thermistor, and the short bottom tube is the gas

exhaust.

4. Disconnect the IRGASON temperature sensor from the EC100 and

connect the shroud temperature sensor in its place.

5. Connect the EC100 to a PC with the EC100 USB cable (p/n 26561).

6. Resume power to the EC100. Wait for all the Gas and Power LED status

lights on the EC100 panel to turn green.

7. Launch ECMon, select the appropriate USB port, and click Connect. The

main screen should now be reporting real-time CO

and H

concentrations. Click Zero/Span. A graph will appear in the lower half

of the zero-and-span window showing measured CO

and H

concentrations (see Figure 9-4).
