WARNING:
o
Do not carry the IRGASON by the arms or the strut between the arms. Always hold it
by the block, where the upper and lower arms connect.
o
Handle the IRGASON carefully. The optical source may be damaged by rough
handling, especially while the analyzer is powered.
o
Overtightening bolts will damage or deform the mounting hardware.
l
CAUTION:
o
Grounding the EC100 measurement electronics is critical. Proper grounding to earth
(chassis) will ensure maximum ESD (electrostatic discharge) protection and improve
measurement accuracy.
o
Do not connect or disconnect the gas analyzer or sonic connectors while the EC100 is
powered.
o The SDM, USB, and RS-485 output options include IRGASON diagnostic data. Be
aware that the absence of diagnostic data in the analog output option could make
troubleshooting difficult and may lead to the user not being aware of potential
problems with the instrumentation (see
EC100 outputs (p. 27)).
o
Resting the analyzer on its side during the zero-and-span procedure may result in
measurement inaccuracy.
o
When cleaning the gas-analyzer window, make sure the alcohol and any residual
water completely evaporate before proceeding with the zero-and-span procedure
(see
Gas analyzer window cleaning (p. 34)).
3. Initial inspection
Upon receipt of the IRGASON, inspect the packaging and contents for damage. File damage
claims with the shipping company.
4. Overview
The IRGASON is an in situ, open-path, mid-infrared absorption analyzer integrated with a three-
dimensional sonic anemometer. The gas analyzer provides measurements of absolute densities
of carbon dioxide and water vapor, while the sonic anemometer measures orthogonal wind
components.
