It is important that the sample airflow system is leak-tight and not
pressurized over ambient pressure. Regular leak checks should be
performed on the analyzer as described in the maintenance schedule,
Table 10-1. Procedures for correctly performing leak checks can be found
in Section 10.3.6.
Relative Pressure versus Absolute Pressure
In this manual vacuum readings are given in inches of mercury absolute
pressure (in-Hg-A), i.e. indicate an absolute pressure referenced against
zero (a perfect vacuum).
