Ideally, the pressure of the sample gas should be at ambient pressure (0 psig).
Maximum pressure of sample gas should not exceed 1.5 in-Hg over ambient.
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 before it enters the analyzer. This vent line must be:

Pneumatic Connections–Basic Configuration–Using Bottled Span Gas
1. Attach a sample inlet line to the sample inlet port. The SAMPLE input line
should not be more than 2 meters long.

At least 0.2m long

No more than 2m long and vented outside the shelter or
immediate area surrounding the instrument.
2. Attach sources of zero air and span gas (see Figures 3-3 through 3-8
inclusive).

Span Gas is a gas specifically mixed to match the chemical composition
of the type of gas being measured at near full scale of the desired
measurement range.
In the case of CO measurements made with the Teledyne Instruments Model
2
T360 Analyzer it is recommended that you use a gas calibrated to have a CO
content equaling 80% of the range of compositions being measured.
