3. The 5830 sample system's design provides a means of challenging the
analyzer with a known source of dry gas to both validate the baseline
readings and to compensate for any minor changes in background
offsets. In addition, the analyzer contains a permeation tube-based
moisture standard that can be used to challenge the analyzer with a
known moisture concentration. As such, the Model 5830 is designed
to deliver reliable, long-term performance from the QCM-based sen-
sor.

Normal operation of the Model 5830 analyzer uses an internal bypass,
which increases the response speed of the system. However, the 5830 is
capable of running in a gas-saver mode as well, which allows the analyzer
to run on a sample volume of approximately 150 SCCM.
In normal operation of the analyzer, the sample gas enters the analyzer
and flows directly through the diaphragm valve (DV2); the other two dia-
phragm valves (DV1 and DV3) remain closed to isolate the first dryer.

There are four separate sample paths in the 5830 analyzer manifold.
The first is a simple bypass that allows for an increased flowrate of

sample gas. This means that when you open the bypass valve (SV1),
