Model Designations
The Model 2000A-EU is ordinarily custom programmed at the factory
to fit the customer’s application. Many parameters, including the number of
channels, the gas application, the materials specification of the sampling
system, and others, are options. The most common options, are covered in
this manual. See the Specific Model Information checklist in the front pages
of this manual for those that apply to your Model 2000A analyzer. Some
standard models that are not covered in this manual are listed here.
Models 2000B:
NEMA-4, bulkhead mounted enclosure for general
purpose, nonhazardous environments.
Models 2010:
Split architecture models using a sealed explosion-proof
enclosure for the Analysis Unit and a general purpose
remote Control Unit for installation in a safe area.
Models 2020:
Both the analysis section and control unit are in a single
explosion proof enclosure.

Front Panel (Operator Interface)
The 2000A is housed in a rugged metal case with all controls and
displays accessible from the front panel. See Figure 1-1. The front panel
has thirteen buttons for operating the analyzer, a digital meter, and an
alphanumeric display. They are described briefly here and in detail in the
Operations chapter of this manual.
Function Keys: Six touch-sensitive membrane switches are used to
change the specific function performed by the
analyzer:
