1. Attach a sample inlet line to the sample inlet port. The SAMPLE input line should not be more than 2
meters long.
NOTE
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:
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 CO2 measurements made with the Teledyne Instruments Model 360E Analyzer it is
recommended that you use a gas calibrated to have a CO2 content equaling 80% of the range of
compositions being measured.
