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.
