3.4.2.1.Sample Gas Source

Attach a sample inlet line to the SAMPLE inlet port. The sample input line should not be more than 2 meters long.

Maximum pressure of any gas at the sample inlet should not exceed 1.5 in-hg above ambient pressure and ideally should equal ambient atmospheric pressure.

In applications where the sample gas is received from a pressurized manifold, a vent must be placed on the sample gas before it enters the analyzer.

3.4.2.2.Calibration Gas Sources

The source of calibration gas is also attached to the SAMPLE inlet, but only when a calibration operation is actually being performed.

NOTE

Zero air and span gas inlets should supply their respective gases in excess of the 800 cc3/min demand

of the analyzer.
