Getting Started
Sample Gas pressure must equal ambient atmospheric
In applications where the sample gas is received from a
pressurized manifold, a vent must be placed as shown to
equalize the sample gas with ambient atmospheric pressure
If your analyzer is equiped with wither the Zero/Span Valve Option (Option 50) or
the Internal Zero/Span Option (IZS - Option 51), the pneumatic connections should
be made as follows:

Once the appropriate pneumatic connections have been made, check all pneumatic
fittings for leaks using the procedures defined in Section 9.3.4.
