3.4.2.3. Input Gas Venting
The span gas, zero air supply and sample gas line MUST be vented in order to ensure that the gases input do
not exceed the maximum inlet pressure of the analyzer as well as to prevent back diffusion and pressure effects.
These vents should be:
At least 0.2m long;
No more than 2m long and;
Vented outside the shelter or immediate area surrounding the instrument.
3.4.2.4. Exhaust Outlet
Attach an exhaust line to the analyzer’s EXHAUST outlet fitting. The exhaust line should be:
PTEF tubing; minimum O.D ¼”;
A maximum of 10 meters long;
Vented outside the M300E/EM Analyzer’s enclosure.
NOTE
Once the appropriate pneumatic connections have been made, check all pneumatic fittings for leaks
using the procedures defined in Section 12.3.3.
NOTE
For information on attaching gas lines to M300E/EM Analyzers with various calibration valve options,
see Section 5.6.
3.5. INITIAL OPERATION
